Alessandra Ambrosio to wear 'Fantasy Bra' at Victoria's Secret show

In an online video entitled "Victoria's Secret Angels Talk Seduction," it was accidentally revealed that Alessandra Ambrosio will receive the high honor of walking down the runway in the bejeweled brassiere, the Huffington Post reports.

The video was leaked when somebody at the retailer posted the video that included a clip of Ambrosio wearing the "Fantasy Bra." Not long after people noticed the gaffe and shared the news via Twitter, Victoria's Secret cut the clip out of the film, Page Six reports.

The "Fantasy Bra," created by London jewelers each year, has become a coveted modeling honor, and only big names have been chosen to wear it ever since Claudia Schiffer modeled the inaugural "Million Dollar Miracle Bra" in 1996. Since then, Heidi Klum, Gisele Bundchen, Tyra Banks and, most recently, Miranda Kerr have all reached it-Angel status by wearing the ornate lingerie on the catwalk -- so you can imagine how this really puts a damper on Victoria's Secret's hype plans for the December 4th fashion show.
