After rocking out in Vegas last week on her actual birthday, Paris dined with the likes of Nicole Richie, Courtney Love and Paula Abdul at The Prime Grill. The party then moved to Hilton's home, where a decidedly less glamorous crowd gathered to party. "Celebs" in attendance included "90210" turned "Dancing with the Stars" stud Ian Ziering (BTW- that guy is 42 years old, almost twice as old as the birthday babe), "Napoleon Dynamite" sidekick Efren Ramirez, both Greasy and Gummi Bear and one of Hugh Hefner's three girlfriends. Hilton's publicist Elliot Mintz was there as well, showing up with one of the worst-wrapped gifts in birthday history.
One wild fan also showed up, going crazy over Paris' mom Kathy, screaming, "Your daughter's my idol dude!" and "take a picture of me and her" at the Hilton matriarch. Kathy quickly put the Paris-ite in her place though, correcting her grammar like a middle school English teacher.
