Heidi Klum
Despite insisting that she was only hosting the annual Victoria's Secret Fashion Show, Heidi Klum ended up back on the runway -- after giving birth to her fourth child, daughter Lou, last month.

Klum told PEOPLE before the show that she still has some weight to lose. "I embrace that I have more curves right now. I'm definitely one of the heaviest of the bunch of the 30 girls in the show."
