Bruno Mars, Rihanna, Bieber to Rock Victoria’s Secret Fashion Show in December

It's probably safe to say that only one of them actually uses the company's products, but Bruno Mars, Rihanna and Justin Bieber will be the musical guests for this year'sVictoria's Secret Fashion Show TV special, according to People magazine.

All three artists will perform as the company's scantily-clad models sashay down the runway, modeling the latest looks in lingerie.  Bruno will likely perform his new single "Locked Out of Heaven," as well as other hits.  Rihanna's new single, "Diamonds," will be a great soundtrack to the company's annual unveiling of its diamond-studded holiday "Fantasy" bra.  As for Justin, watching him serenade gorgeous models with "Boyfriend" may just be too much for Selena Gomez to take.

The Victoria's Secret Fashion Show will air December 4 at 10 p.m on CBS.
