...Hyde was celebrating itself! That's right - despite lingering rumors of its demise as a hip spot, Hollywood's reigning nightlife institution turned one last night, and all the stars turned out to celebrate its birthday. We caught Rumer Willis, Jessica Alba, Caroline D'Amore...the list just keeps on going! We even spotted Paris Hilton stopping by for a duty round at her home-down-the-hill-from-home! Hopefully the embattled heiress enjoyed herself - given the serious turn her life's taken, she could probably stand to blow off a little steam!

Elsewhere, we caught Courteney Cox and Selma Blair dining at Il Sole - separately, of course.
