Pop singer Rihanna was Unapologetic about doing what she does best last night--selling her sex appeal.  She strutted down the catwalk with dozens of hot models for the 2012 Victoria's Secret show taped in NYC.  See video and the hot photos inside....

Last night, international pop chick Rihanna walked the pink carpet at the Lexington Avenue Armory for the annual Victoria's Secret fashion show. The show, which featured performances from Rihanna, Justin Bieber and Bruno Mars, will air Dec. 4.

She did tons of press to promote the upcoming release of Unapologetic, including an interview with EXTRA correspondent AJ Calloway.

Then chick hit the runway in the sexiest get-ups she could find (and that will be allowe don network tv):

She rocked a black corseted gown with a thigh-high spilt (revealing a garter belt).  Rocking lace gloves, a pearl choker and matching rare vintage Chanel pearl sunglasses from Depuis 1924 ($3200), she performed her single "Diamonds."  

She still managed to be the center of attention showing off those legs & that skin, even when standing next to Doutzen Kroes.

Supermodel Joan Smalls also shined bright like a diamond on the catwalk.  And later....she went up in flames with rings of fire.

As for Rih's change-ups:

She also rocked a sheer pink mini to belt out "Fresh Out The Runway."

She got so caught up in seeing the pretty models and lingerie that she had to reach out and touch it for herself.  Y'all know how she does it.

At the end of the show, she greeted her adoring fans, alongside the models, at the end of the catwalk.

And the view from backstage.....

Rih Rih kicked it with the gorgeous models tweeting #LEGITmodelShit I'm a #VS girl now lol  She summed up the "experience" of being backstage saying, "1 big room, full o bad bitches."  Sounds about right.

Fun times!
