Sizzling Pictures of Victoria's Secret Fashion Show 2012; Supermodels Heat Up the Ramp [PHOTOS]

The much-awaited annual lingerie show - Victoria's Secret Fashion Show 2012 - kicked off on Wednesday night at the 69th Regiment Armory in Manhattan, New York with some of the world's hottest supermodels from Adriana Lima to Alessandra Ambrosio to Karlie Kloss to Erin Heatherton walking the ramp in sizzling and breathtaking lingerie collections of the brand.

Adding spice to the already hot lingerie show, Rihanna, Justin Bieber and Bruno Mars belted out some of their favourite numbers. Rihanna donned a lingerie-like outfit and matched the top models even as she sung "Diamonds", from her upcoming album "Unapologetic", and "Fresh Out the Runway".

The models appeared in different outfits during the show which has several segments like Circus, Angels in Bloom, Dangerous Liaisons, Calendar Girls and Silver Screen Angels.

Brazilian model Alessandra Ambrosio, 31, was given the honour to wear the Floral Fantasy Bra designed by London Jewelers. Embedded with 5,200 precious and semi-precious stones, the Fantasy Bra is worth $2.5 million.

Miranda Kerr, 29, who has been declared the sexiest woman alive by Esquire UK, looked stunning in a forest green creation embedded with sparking stars and branch-like lines stretched as far as the tinny lingerie could take.

Other models like Doutzen Kroes, Candice Swanepoel, Lily Aldridge, Behati Prinsloo, Izabel Goulart and Erin Heatherton looked equally stunning in the latest lingerie collection of Victoria's Secret brand.

The Victoria's Secret fashion show 2012 also paid tribute to the victims of the recent Superstorm Sandy by letting Lily Aldridge flew the American flag down the ramp. In fact, Victoria's Secret and CBS donated $1 million each towards the Sandy relief.

The Victoria's Secret fashion show 2012 will be aired on CBS on December 4.
