Paris Hilton parties so hard she rips her dress in Las Vegas

Paris Hilton didn't let her super-tight dress stop her from showing off her dance moves as she partied in Las Vegas.
But after choosing such an unforgiving mini-dress to dance in, its perhaps no surprise to see the outfit didn't last the night.
As the hotel heiress threw some shapes at the Vanity Lounge nightclub over the weekend, it quickly appeared her thin Lycra sleeve started to rip from all movement.

The Simple Life star showed off her svelte figure in a sparkly black asymmetrical mini-dress, which showed the strain as the sleeve ripped in several places.
Clearly in the party mood, Hilton jumped up and danced on the white leather sofa of the VIP area, watched by her boyfriend Doug Reinhardt.
Hilton and her on/off boyfriend Reinhardt joined a host of friends to celebrate the launch of ParisHilton.com over a long weekend.
The couple, who have dated on and off for 11 months, stayed at the penthouse suite in the new Paradise tower at the Hard Rock for three nights.
They arrived on Friday after getting a private jet from Los Angeles, which Hilton posed in for a picture on her Twitter micro-blogging page.

Hilton regularly updated her Twitter during the weekend: 'We be clubbin'...
'We had the best time at Vanity last night. Such an amazing night club. :)'
The launch of Hilton's website comes six years after she leaped to international fame on the internet with the release of her sex tape 1 Night In Paris with ex-boyfriend Rick Salomon.
Hilton is hoping the new site will align her many business ventures, including fashion, accessories and perfume line.

She also hopes to promote her personal appearances and potential acting and singing work on the site.
She said: 'I am so thrilled that with this launch I can now directly reach my fans around the world and bring them the most up to the minute news, entertainment and accurate information on everything we are working on at Paris Hilton Entertainment.
'I'm very passionate about social media and new technology and plan to continually find new ways to innovate and bring my fans the most exciting and fun ways to communicate, share and learn together. I'm so excited to get started.'
Hilton recently explained her empire with the launch of her sixth fragrance Siren.
