Paris Hilton parties with Britney Spears' ex

Here was Paris Hilton at the opening of an envelope in Las Vegas on Saturday night.

Actually, it wasn't so much 'an envelope' as 'the nightclub and restaurant Lavo'. And none other than Kevin Federline, the man formerly known as Britney Spears' husband, was also there.

As you can see, Paris posed for America on the red carpet, sporting a lemon-coloured dress, metallic shoes, hair extensions and a terribly shiny face.

Unfortunately, however, what poses in Vegas doesn't stay in Vegas - and I'm sure Paris is going to be popping up in LA again any day now...
