Adam Lambert is usually the life of the party, but getting too lively at one bash got him thrown out! Pop star Lady Gaga was celebrating her 25th birthday at La Cita Mexican restaurant in L.A. last week when the “American Idol” runner-up strolled in obviously inebriated.

According to gossip blogger Perez Hilton, “Adam showed up beyond drunk. Super sloppy embarrassingly drunk!” How embarrassing? Lambert punched a hole in the restaurant’s ceiling with his fist-pumping! A source told US magazine, “Adam acted like an animal. He kept jumping up on the tables and chairs and screaming. When they brought the cake out he tried to smear it in Gaga’s face and put a doll from the cake in her mouth!”

This was the last straw for the birthday girl, who had Lambert ejected by security. Hint to Lambert and other pop stars who think they can get away with anything—just being halfway famous doesn’t mean you’re welcome everywhere.
