Paris 'not preggers'

Paris Hilton has squished any rumours that she might be pregnant with boyfriend Benji Madden's baby by partying in Las Vegas.

The heiress hit Tao night-club with her new BFFs - a bunch of mini-skirted girls auditioning to be Paris' 'best friend forever' as part of yet another reality show.

Looking sleek, toned and tanned in a black halter-neck dress, the 27-year-old socialite showed off a trim tummy with no sign of the 'baby bump' apparently visible when she stepped out in green satin last week.

Paris was also spotted knocking back vodka and tequila at an after-party held at a friend's house, a guest told People magazine, so unless she has a bizarre approach to ante-natal nutrition we think it's safe to say she is not yet set to be the next celeb yummy mummy.

Watch this space though, Paris' former BFF and fellow Simple Life star Nicole Richie recently had her first baby - with Benji's brother Joel Madden. Surely fashion-follower Paris is not one to fall behind on a trend…
