Adam Lambert got one heck of a birthday gift from actor David Arquette -- a lap dance!

Lambert was celebrating his 31st birthday a few days early (his actual b-day is Jan. 29) at a party on Friday night (Jan. 25). He was joined by pals at Bootsy Bellows night club in West Hollywood, and Arquette, who's one of the co-owners of the club, was one of the lucky members of the entourage. He stripped down to his skivvies to show Lambert just how much he loves him, much to Lambert's delight -- and even tweeted about it the next day! Sounds like one heck of a night. Happy early birthday, Glambert!
