"I got drunk with my gays its not murder," she said on Twitter. "Everyone kept sending us drinks. I was being polite."
The Real Housewives of Beverly Hills star suffered a wardrobe malfunction as her male friend attempted to escort her inside the hotel.
She wound up flashing a bit of her boob and her black thong as she exited her car, but fortunately her pal was there to help her make a quick recovery.
Of course, the photogs still managed to capture numerous pics of the 40-year-old accidentally showing off some major skin.
But Glanville had something else to say to the haters who were criticizing her behavior.
"When ur PERFECT and make all the right decisions ALL the time, and don't have at least a bit of cellulite on ur ass, get back 2 me," she said.
If there's one person who undoubtedly disapproves of Glanville's late night outing, it's Real Housewives of Atlanta star NeNe Leakes.
After all, during her Watch What Happens Live: NeNe One-On-One special back in May, Leakes wasn't afraid to share how she really felt about her fellow Bravo star.
"Brandi's just a train wreck. Just a wreck. Just a wreck," Leakes said at the time. "She's just off the chain, she's off the hook [with] a lot of the things that she has to say, just so talkative."
Glanville offered a final message to her fans before moving on from the subject entirely.
"It's a new day can we please keep it positive," she said. "I'm not perfect but I do the best that I can."
