Laura may have mysteries... but Debra puts it all out in the open!
You twerk those hips, lady!
But it seems that Dem was also grindin' her cougar ass up on ANOTHER man during the event, the seXXXy Lenny Kravitz (above)!
"[Demi] was most ready to party than anyone else in the room."
Demi was apparently acting VERY hyper all evening — she was seen clutching an energy drink most of the night — and constantly cozied up to Lenny on the couch while she wan't trying to stick her bum-bum in his face.
Well, we're glad Demi is obviously letting loose, and girl seemed to be having a ballz-to-the-wall good time…
But we hope Dems didn't have a little TOO much fun, you know, indulging in certain alcoholic/druggy poisons and whatnot!
