This year it's hot Victoria's Secret model (and mother of two!) Alessandra Ambrosio, 31, who gets a shot at wearing the famous $2.5 million Fantasy Bra in the highly anticipated final moments of the annual Victoria's Secret Fashion Show in December.

While the design of the bra always changes, as does the model who dons it, the mystique of the annual million-plus-dollar undergarment, which launched with model Claudia Schiffer in 1996, doesn't change. This year the "Floral Fantasy Bra" has a floral theme, featuring pink, white and yellow diamonds arranged in shapes of flowers. A detachable ornament with five petals dangles from the cleavage, and the entire bedazzled piece comes with a matching belt.

Ambrosio joins the ranks of lucky ladies Heidi Klum, Gisele Bundchen, Tyra Banks, Adriana Lima and Miranda Kerr, who have each modeled some version of the fantasy bra before — some more than once.
