Rihanna spent some time in "1 big room, full o bad b*tches" Wednesday night at the Lexington Avenue Armory in New York City during the taping of the 2012 Victoria's Secret lingerie show. The singer, along with Justin Bieber, performed while scantily clad models such as Miranda Kerr, Adriana Lima, Karlie Kloss and Candice Swanepoel walked the runway in their tiny little outfits.

Only difference between RiRi & Biebs though? She got to hang out with the models backstage, and she posted plenty of pictures.

Wearing a sexy strapless black gown with a slit up one side to reveal her thigh-high stocking and garter and a pair of black lace gloves, the singer escorted model Doutzen Kroes down the runway while singing her latest hit, "Diamonds."

She also posed with the likes of Jasmine Tookes and Cara Delevingne, Izabel Goulart. Summed things up for an overexposed shot with Lily Aldridge though; writing, "b*tches pretty in pink."

After the show she showed off what was underneath her dress when she got back to her trailer, posting a topless photo of herself on the couch wearing thigh-highs held up by garters, a pair of ankle boots and nothing else. She lit up a cigarette (we assume it's a cigarette, but knowing Rihanna it's probably not a cigarette) and wrote, "And that's a wrizzap."
