A celebrity gossip site commented that either Heidi Klum is hiding a super secret diet regimen or she must be an alien. Because she looks like this just five weeks after giving birth to her fourth child:

This photo was taken on November 21 during the Victoria’s Secret Fashion Show in New York. She was supposed to be hosting the show but reportedly became the biggest crowd-pleaser when she made a surprise runway appearance.
