Victoria's Secret angel Alessandra Ambrosio showed off this year's $2.5 million fantasy bra, which she will wear on the fashion show in Deember.

In their official Facebook fan page, Victoria's Secret published photos of Alessandra as she presented the Floral Fantasy Bra Gift Set and Bombshell Fantasy Fragrance, designed exclusively for Victoria's Secret by London Jewelers, at the ultimate Victoria's Secret Herald Square store in a Press Day designed to showcase the new products.

This is the first time Alessandra has been awarded the prestigious honor of wearing a Victoria's Secret Fantasy Bra, following in the footsteps of the most legendary supermodels that have received the honor in years past: Tyra Banks, Gisele Bundchen, Heidi Klum, Adriana Lima, Marisa Miller, Miranda Kerr and Claudia Schiffer among others.

Alessandra will wear the bra on the runway in the Victoria's Secret Fashion Show, airing December 4th on the CBS television network.

Valued at $2.5 million, the Floral Fantasy Bra Gift Set is handset with over 5200 precious gems, including amethysts, sapphires, tsavorite, rubies, white, pink and yellow diamonds, all set in 18 karat rose and yellow gold.

The gift set includes a custom Very Sexy Push-up Bra and matching belt. The bra has two removable diamond flower pins and the drop centerpiece features an astonishing 12.5 carat and 20 carat white diamond.

Along with the Floral Fantasy Bra Gift Set, Victoria's Secret debuts the $500K Bombshell Fantasy Fragrance this holiday season. It's the brand's award-winning Victoria's Secret Bombshell Eau de Parfum perfect for the holidays.

The fragrance has notes of purple passion fruit, Shangri-la peony and vanilla orchid. The bottle is comprised of white, pink and yellow diamonds, sapphires, tsavorite, rubies plus a 10 carat white diamond and an exquisite one of a kind, hand carved tourmaline butterfly.

Over 15,000 stones from around the world were inspected to find the perfect colored, size and shaped gems to create the one of a kind bra, belt and fragrance bottle. These fantasy gifts were inspired by the idea of dreamy fantasy garden filled with vibrant colored flowers and heavenly Angels.

Victoria's Secret will also launch a free holiday app that allows one to experience the magic of the Christmas Dreams & Fantasies Catalogue on their iPad. The Victoria's Secret Holiday App brings interactive features and exclusive content to every page including Angel interviews, fun facts from the shoots, behind-the-scenes videos and beauty how-to's.
