Looks like bad behavior does not sit well with Lady Gaga. Adam Lambert found that out the hard way when he was kicked out of her birthday party for being drunk and unruly.

Close friends of Gaga threw her a surprise birthday party to celebrate her 25th birthday at Mexican restaurant called La Cita Bar in Los Angeles and UsMagazine.com is reporting that even though Lambert was not one of the invitees, he attended as a guest of the music group the 'Scissor Sisters'.

Celeb blogger Perez Hilton told Morning Dish radio program on Thursday that "Adam showed up beyond drunk. Super sloppy embarrassingly drunk!"

Hilton also revealed that Lambert began some intense fist-pumping and kept beating on the walls until he actually punched a hole in the bar's low ceiling.
