Heidi Klum stepped out on the runway at the Victoria's Secret fashion show Thursday night, just five weeks after giving birth to daughter Lou Samuel. This isn't her first post-baby public appearance. She showed off her thighs in fishnets and thigh-high boots when she dressed up as a crow for Halloween with husband Seal. Klum said on Wednesday that she still needs to lose 20 pounds, but she looks pretty good here in her runway corset, an LBD she wore on the red carpet and a body-hugging leather dress she slipped into for the after party.
