Looks like we've discovered the secret to Bar Rafaeli's buff body: the supermodel posted these pictures of herself on Twitter, smothered head-to-toe in mud from the Dead Sea.
The Israeli-born model was enjoying a trip home, when she stopped to indulge in her rather messy beauty regime - which involved covering her face, limbs and bikini-clad body in the supposedly skin-enhancing mud.
"*Muddy* but feels good!!" she Tweeted. "DEAD SEA - if you haven't been... well, sucks for you!"
