No, that isn't the number of men Paris Hilton went home with last night, at least not that we know of.
Instead, it's the age our favorite talentless heiress turns today. Hilton threw a party in her own honor last night, inviting friends and family to New York City club Butter.
Looks like she had some trouble getting there, however. It's so hard to find a good driver these days...
Past Paris lovers and new Paris friends, such as Stavros Niarchos and Aubrey O'Day, turned out for the event.
