Klum: "Pregnancy is a miracle"

Heidi Klum has described pregnancy as a "miracle".

The supermodel, who is currently expecting her fourth child, admitted that the final month is the worst.

"The last month is unbelievable, how rapidly your stomach goes," she told Page Six. "It's huge. The thighs, the butt - everything explodes in the end."

However, she added that it is "bizarre" how quickly she can regain her figure after giving birth.

"Just as it's a miracle that you can grow a human being in your belly, it's a miracle that your body goes back to normal again," she said. "I don't think you ever get back to exactly the way you were, but you do get close.

"And I'm happy with that. Especially when you see your kid for the first time."
