While the 2012 Victoria's Secret Fashion Show won't air on CBS until Dec. 4, Justin Bieber, Rihanna, Bruno Mars and the Angels all hit the runway in N.Y.C. to pre-tape the show on Nov. 7. Biebs, RiRi and Bruno performed some of their newest hits alongside super models like Maud Welzen and Lily Aldridge at the Lexington Avenue Armory, with all three of the entertainers interacting with the glitzy, winged lingerie models while singing.

Bieber looked like he was in all of his teenage glory as he joked around with the Victoria's Secret models during songs like 'As Long As You Love Me,' which he performed acoustically, and the high-energy 'Beauty and a Beat,' an appropriate choice of song whilst surrounded by such lovely ladies. He showed up on the red carpet in black, but swapped those duds for his white performance gear, shedding his vest to show off his arm models.

Meanwhile, the gorgeous (and tall -- she's 5' 8") Rihanna blended in perfectly amongst the models at the 2012 Victoria's Secret Fashion Show. She showed up on the red carpet in a cute satin, midriff-bearing top and skirt, but went full-blown diva with her 'Diamonds' performance outfit, flashing tons of thigh in her sexy black ballroom gown and putting on some round, bedazzled shades. Later on, she showed off her bra in a lacy pink number while belting out a new track called 'Fresh Out the Runway' (see multiple spellings) She looked really awesome dancing around and giggling with the flowery Angels.

Finally, Bruno Mars took the stage to perform new songs off of 'Unorthodox Jukebox,' like his latest hit, 'Locked Out of Heaven.' Before he hit the runway, the pint-sized crooner tweeted, "Shh--tttt U aint gotta be tall to sing to some super models...... or do u?" The answer is "no," because Mr. Mars and his backup band totally rocked it during their 'Calendar Girls' set, where they sang to models dressed for various seasons.
