Drunk Adam Lambert Gets Kicked Out of Lady GaGa's Birthday Bash

 Adam Lambert didn't left Lady GaGa's 25th birthday party last Sunday night, March 27 the usual way. Us Magazine has uncovered that the "American Idol" alum came to join the celebration already drunk and managed to force the birthday girl to ask security guards to kick him out after he showed off rowdy behavior during the bash.

In a interview with Morning Dish radio program, celebrity blogger Perez Hilton revealed that the 29-year-old singer was actually not invited to the bash. Still, he came as a guest of the Scissor Sisters, who are GaGa's opening act on tour. Perez further recalled, "Adam showed up beyond drunk. Super sloppy embarrassingly drunk!"

During the bash, Adam also left a hole in the low ceiling of La Cita Mexican restaurant in Los Angeles. An eyewitness 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!"

Adam's drunken behavior apparently didn't stop there. Perez added in his Thursday, March 31 interview that the "Whataya Want from Me" singer then tried to serenade GaGa "like he was auditioning for Idol again!"

A day before Perez's interview, Adam took to Twitter to admit his bad behavior on the party. On Wednesday, March 30, he wrote two tweets that read, "My hand still hurts. LoL" and "Was trying for celebratory gesture 4 gaga's B- pinata style...instead my fist is all bruised and la cita has a hole in the ceiling. #sloppy."
