Jennifer Lopez is savouring every moment with her much younger backing dancer beau Casper Smart.

The two partied the night away yesterday at Hyde nightclub in the Bellagio Hotel & Casino in Las Vegas as they celebrated the launch of her new single Goin' In.

The superstar diva, 42, arrived at the event dressed to the nines in a form-fitting metallic and white mini dress that showed off her toned legs to perfection.

He's all grown up! Justin Bieber, 18, seals the $6.5m deal on his very first home - a sprawling Calabasas mansion

At the age of 18, most teenagers are saving up for their very first car.

But for multimillionaire Justin Bieber, he had his eyes set on his very first home.

And he has found it in the heart of the upscale neighbourhood of Calabasas.

Sealing the deal: Today the pop sensation sealed the deal on a $6.5m mansion in the Californian suburb, where the Kardashian family also live

Today the pop sensation sealed the deal on a $6.5m mansion in the Californian suburb, where the Kardashian family also live.

According to the Los Angeles Times, he laid down the large sum for a 10,000-square-foot home on 1.3 acres. 

Justin's new home features a a library, a movie theater with stadium seating, a wet bar and a wine cellar, and the grounds include a pond. 

The property previously belong to Eddie Murphy's ex-wife Nicole.

The purchase comes after Bieber had been looking for a new home for some time, narrowing down his search to three properties.

At one point he was thought to have been eyeing up the home currently being rented by Ashton Kutcher.

Boasting a large pool, a huge guest house and an ample garage, it is likely the singer's girlfriend Selena Gomez will be spending a considerable amount of time there.

It is also likely the star will be splashing the cash to make the property state-of-the-art, including installing the latest high-tech gadgets.

Al fresco dining: The property also house a lovely outdoor area perfect to entertain

Reports earlier this year suggested Bieber hopes to instal a computerised system which will allow him to have control of his home at his fingertips, from the bathtub to the blinds.

He is also said to be planning to install his own home cinema theatre as well as a games room - described as a 'teenage boy's bedroom' - featuring the latest consoles and old arcade machines.

The purchase comes as Justin seemed to lose his cool with the paparazzi today.

The Boyfriend singer appeared to grow angry at photographers snapping him and girlfriend Selena Gomez.

He then appeared to lose his temper and was reportedly involved in an altercation.

However while Justin failed to keep calm in the situation, Selena made up for his shortcomings.

The 19-year-old helped Justin retrieve his baseball cap and one of his high top trainers after they flew off during the incident.

She also appeared to be saying some soothing words to her beau as she chatted to him while tenderly stroking his arm to calm him down.

However the level-headed starlet did look a little concerned during the ordeal.

Meanwhile Justin had a face like thunder as he put his shoe back on while being comforted by his girlfriend.

Justin then walked away with his head in his hands seeming somewhat embarrassed at his behaviour.

The incident occurred as the pair were making their way to a cinema to enjoy a movie date.

Along with his plum-coloured hat and trainers that had flown off, Justin was sporting an aquamarine T-shirt and black jeans.

And Selena looked summery in a printed monochrome maxi dress with a split up one side, which she teamed with brown sandals.

Mail Online has contacted a representative for Justin Bieber for comment.

Why the big secret? Justin Bieber and Selena Gomez go for lunch date but sneak out the back door looking grumpy

Justin Bieber and Selena Gomez have been dating for over a year now and have been seen making out in public and being openly affectionate with each other.

But the teen couple appeared coy as they left Benihana restaurant in Sherman Oaks, California yesterday.

The loved up twosome sneaked out of the back door of the establishment with the Baby singer seemingly trying to cover his face with his baseball cap.

Justin led the way and held Selena's hand as they walked towards their vehicle.

Selena didn't raise a smile and looked dressed down in grey jeans, a neutral-coloured sweater and sandals. 

Meanwhile, the pint-sized pop star wore baggy sweats, a grey T-shirt and trainers.

There had been recent speculation that the pair had split up after they hadn't been seen together for a while and Justin's resistance about speaking of Selena during a recent trip to the Ellen DeGeneres show.

Puppy love: The couple recently reunited after spending a few weeks apart

But the pair seem to be firmly together although they did not appear to be in the best of spirits.

However the teen lovers had a passionate reunion at Los Angeles' LAX airport last week after being away from each other a few weeks.

But the teen heartthrob has a lot to learn about the language of love.

Rather than greet Selena himself, the Love Song singer was met and escorted by a bodyguard to a waiting van that had Bieber inside it playing the video game, Mortal Kombat.

The Spring Breakers actress was surely glad to be home as she had been caught in a 5.9-magnitude earthquake in Bulgaria's capital Sofia last week while filming The Getaway.

Selena assuaged the fears of her fans in a tweet that came Tuesday afternoon.

'Thank you for all of your concerns!! Earthquake was scary but thankfully everyone is ok. Praying for Italy,'  she wrote on her Twitter profile.

From the look on the singer's face she had missed Justin desperately and the couple embraced passionately in the back of the van before speeding off into the night

Home sweet home: The pair have been separated for weeks

Selena looked shaken and flushed as she walked out to the waiting van.

Wearing a crocheted blue top, ripped jeans and sheepskin boots, the teen starlet admitted that she had been scared by the incident although no immediate deaths or injuries were reported.

The Getaway also stars Ethan Hawke and is a remake of the classic 1972 flick of the same name, which saw Steve McQueen and Ali MacGraw play the lead roles.

Bieber made something of a statement about his good fortune yesterday with a T-shirt that played up to his diva reputation.

The Boyfriend singer was seen stepping out of a recording studio sporting a top emblazoned with the words ‘Doing real stuff sucks’.

However Justin clearly does value his work ethic and posted on Twitter today: '[You] gotta put in the work if you want the results.'

Justin teamed the cocky T-shirt with an appropriate pout as he left the studio in California today.

The star was also wearing a pair of baggy charcoal jeans held up by a Louis Vuitton belt, a red baseball cap and matching Converse trainers.

David Beckham is viagra for the modern woman! Elle magazine's editor reveals how the footballer sets women's pulses racing

This week, David Beckham will be the first man to appear solo on the front of a woman's fashion glossy. Here, Elle's editor discusses the latest cover star...

There’s a small queue of women waiting nervously to talk to me in the school playground after the morning drop off. My heart beats a little faster as I approach them and I’m aware of the giddiness rising around me. 

‘You can watch it here,’ I whisper to the first in line, and she scribbles down the website address furtively. ‘It’s only ten seconds long but he is topless in a swimming pool,’ I say. ‘I’ll have more for you in a couple of weeks.’

Devoted dad: David Beckham with baby Harper

If you captured this scene on camera, you’d probably assume I was passing on details of an illicit website such is the fervent female interest. But I’m not.

I’m directing women (normal, grounded, intelligent women, with good self-esteem) to watch a video clip starring David Beckham; a man whose persona has reached such heroic proportions that any contact with him provokes an extraordinary reaction. He is without doubt Viagra for a generation of sexually liberated and secretly obsessed women.

I wish I could pour scorn on this crazed female behaviour... but I can’t. Because I’m in love, too. 

‘I just love him so much,’ one of the mums in the playground tells me almost apologetically as she heads off to watch the online teaser clip of the Elle cover shoot starring 37-year-old Mr Beckham. I have never known anything like it in 15 years of working with, meeting and putting celebrities on the cover of glossy magazines. Never before have I been mobbed at the school gates by infatuated women. 

Even a global icon like Madonna, who was on our cover in May 2008, didn’t elicit this kind of interest. But ever since we announced we were featuring David Beckham in our July issue — the first man ever to appear on the Elle cover in its 27-year history — I’ve been bombarded, accosted and courted by women from all areas of my life.

‘Is he as handsome as he looks?’ they ask me bizarrely, desperate for any snippets of the man. I wish I could pour scorn on this crazed female behaviour, I wish I could say ‘get a grip you silly women; he’s just a man’ but I can’t. Because I’m in love, too. 

I broke all the rules for David. Revealing your cover star before the issue goes on sale is a magazine no-no but I couldn’t keep it in. So why did we choose David, the LA Galaxy footballer, Olympic ambassador, H&M model, husband to Victoria and father-of-four as our only male cover star? 

It’s the Olympic Games this year and I wanted to celebrate with a playful nod to the nation’s sporting and patriotic fervour from a fashion magazine.

The front cover of Elle magazine

‘Do you think he will sell copies of a women’s magazine?’ my male CEO asked rather solemnly when I told him of my man-plan. ‘Do you know any women who don’t want to see David Beckham with his shirt off?’ I replied [in my head — after all he is my boss]. Out loud I simply said ‘Yes’. And if the excitement caused by a sneaky picture we posted  on Twitter is anything to go by, I’m right. 

So what was he like? Well, for the record, the Beckham cover was one of the smoothest shoots we’ve ever organised. He was on time, polite and engaging. He asked — and remembered — everyone’s name. He didn’t bother with a changing room; slipping in and out of jeans and T-shirts between takes, in front of a 20-strong crew.

He didn’t mind that it was freezing when we asked him to get into the cool LA pool. And, reader, he was wearing white boxer shorts. I’ll leave that image with you for a minute. 

Sadly, I wasn’t able to go on the shoot and meet him, but listening to the tape of the interview was enough to make me fall in love. He talked so lovingly about his precious baby girl, Harper, that you could hear the whole office sigh collectively. 

Maybe it was when he talked about dropping his boys off at school, or when he admitted, shyly, that he calls Victoria at least five times-a-day because he’s still completely infatuated. 

‘He’s just so good,’ writer Alice Wignall told me after she’d interviewed him over lunch. I’d chosen Alice because she’s sensible, smart and, perhaps, a little cynical even. I thought she’d be immune to any kind of Team Beckham charm offensive, but she came back smitten too. ‘There is no dark side,’ she told me. ‘He loves football and takes it incredibly seriously, he loves his family and he works really hard. Full stop.’ 

But back to reality. Putting a celebrity on the cover every month is the most time-consuming and expensive thing we do on a glossy magazine. It’s also the most important business decision I make, but as with all things in business you can never be sure you’ve made the right call. 

On this occasion, though, I am. In the words of singer Bonnie Tyler, we’ve been ‘holding out for a hero’. And when we found him we put him on the cover.
