Heidi Klum leggings chateau marmont blonde project runway

Heidi Klum was one of the famous faces at a pre-Grammy bash at the Chateau Marmont in West Hollywood on Thursday night, and the supermodel went all out with a leather skirt and knee boots. Hot mama!

Heidi is gearing up to promote the latest season of Germany's Next Top Model, and in between raising four children and settling in to her massive Bel Air pad, we're not sure how she has time to do it all -- and look so fab!
