Exclusive: Heidi Klum & Victoria's Secret Models Invade Times Square!

Only ET was with the always-stunning Heidi Klum, Marisa Miller, Alessandra Ambrosio and the Victoria's Secret Fashion Show beauties as they take a NYC bus ride to Times Square moments before they sashay on the runway!

Heidi, who gave birth only five weeks ago, tells ET she feels like a veteran of the popular fashion show, saying, "I think it's my twelfth year, and I'm super excited to be still part of it."

Marisa will be donning the priciest item -- the Fantasy Bra – and she tells us her plan in case it falls apart onstage!
