The 2013 Victoria's Secret Fashion Show took place in November, but all the sexy action does not air until Tuesday night on CBS.

Last month, the International Business Times along with other members of the press were invited to the Lexington Armory in Manhattan to watch the models get ready for the taping of the show. After wowing us with their charming personalities, 40 models – including the likes of Alessandra Ambrosio, Candice Swanepoel, Adriana Lima, Behati Prinsloo and more – stormed the catwalk for one of the sexiest shows in the brand’s history, with performances by Taylor Swift, Fall Out Boy, Neon Jungle, and A Great Big World.

Since 1995, L Brands Inc.-owned lingerie giant holds an annual fashion show. The show was first televised in 2001, broadcasted nationally featuring notable musicians and the most famous Angels, including Naomi Campbell, Heidi Klum, Liu Wen and Gisele Bundchen. Today, the show garners viewers from over 185 countries around the world.

The "Fantasy Bra," a custom-designed bejeweled brassiere, is another tradition since the first was created in 1996 and worn by Claudia Schiffer. It emerged for the first time on the runway during the annual show in 2001, when Heidi Klum wore the “Heavenly Star Bra.”

This year, the bra cost $10 million and was worn by 23-year-old South African beauty Candice Swanepoel. Designed by jeweler Mouawad, the bra is adorned with more than 4,200 gems from around the world including rubies, diamonds and yellow sapphires and hand-set in 18-carat gold with a 52-carat ruby in the center.

The bra, which is marketed as the ultimate holiday gift L Brands Inc., has never sold since its inception in 1996.

The 2013 Victoria's Secret Fashion Show airs Tuesday night at 10 p.m. EST on CBS, but catch all the sexy action from the models backstage and on the runway before in this 100-photo gallery slideshow.
