Fergie was in Las Vegas last night for a double birthday bash, but this time it wasn't her own [1]. She and Josh Duhamel helped Slash of Guns N' Roses [2] mark his big day with a show and a huge cake [3] while Fergie's dad Pat celebrated his too with a slightly smaller version [4]. Fergie took the stage with the band, which is perfect practice for her upcoming performance at this year's Fashion Rocks [5]. Even more exciting, however, is that Fergie recently signed on for her first major movie role in the musical Nine [6] alongside costars like Nicole Kidman, Kate Hudson and Daniel Day-Lewis. Sounds like a pretty interesting group so we can't wait to see what that one is all about.
