Heidi Klum: Her Amazing Body Evolution
After four(!) kids the supermodel mom, 38, still looks as hot in a bikini as she did the first time she walked at the Victoria's Secret Fashion Show back in 1998.
Klum, who famously returned to the runway just two months after giving birth to son Henry in 2005, admitted that bouncing back post baby gets harder with age.
"Everything changes when you get older. It was different when I was 31 with the first one. Now, being 36 with the fourth one [daughter Lou], it's different." she told Us in 2009.
"For me, it always works to get back into it immediately," she said. "I think that if you wait too long, it kind of sticks on and it stays there forever. I have to be motivated."
