Happy birthday Heidi! Age is nothing but a number for Heidi Klum and she’s proven it by wearing the sexiest red carpet outfits ever throughout her entire career. Whether it’s a sheer ensemble, a teeny tiny mini dress or something with cutouts, Heidi is not afraid to show skin, and considering she always looks so amazing, we definitely do not blame her.

It’s hard to believe that Heidi has given birth to FOUR children, and she still manages to keep up her toned frame and thin figure. Heidi’s first daughter, with Flavio Briatore, Leni, was born in May 2004. After that, she and Seal had three kids together in 2005, 2006 and 2009.

Heidi has been modeling since 1992, so her red carpet poses are the best of the best, and we’ve rounded up some of her hottest red carpet looks of all-time. Keep clicking through to check ’em all out!
