Supermodel Heidi Klum and husband, Seal, renewed their vows this weekend in front of their ever-expanding brood and over 100 friends and family members at Trump's private Palm Beach estate, Mar-a-Lago.

After the ceremony on Saturday (which was a masquerade theme!) the world's best-looking couple spent Sunday on the beach with their four kids, and a ton of sand toys. It was Mother's Day, but the German stunner looked like she didn't have too much time to relax. Maybe that's how she gets her perfectly toned abs and enviable legs, chasing after four kids!

In a gray snakeskin print bikini and gold necklace, the model mom and wife looked fit, happy, and healthy. And of course, her big smile pulled the look altogether.
