Brittny Gastineau -- Are You Looking at My Ass? Seriously, PLEASE Look at My Ass!!

And the gold medal for "Camera Whoring with Your Ass Out" goes to ... Brittny Gastineau -- and this video proves it beyond a shadow of a doubt.

Kim Kardashian's pal appeared to be several drinks in when she poured herself all over a bar at the Fontainebleau Hotel in Miami this weekend -- and slowly undressed while blatantly mugging for paparazzi.

The most awesome part of this video is not Brittny's ass ... but the fact everyone around her is totally ignoring her.

You know how this ends, right? With Brittny passed out, looking like she's auditioning for "Weekend at Bernie's."
