Leonardo DiCaprio might have a s---eating grin on his face in this photo, but it's not from eating it. It's from rinsing it out.

The Scorsese darling is, indeed, a fan of colonics. Who doesn't love water jetting up their behinds?

A source told the Huffington Post, "Leo was introduced to them by [former] girlfriend Erin Heatherton and goes to the Piper Center for Eternal Wellness on Spring Street."

Of course, just so you don't think it's like, totally weird, the source added, "Like a lot of guys, Leo took a while to be convinced to try one.”

Apparently they're like Pringles.

“While he was dating Erin, he went four times and was last seen leaving the center on Aug. 22, but hasn't been back since he broke up with Erin."

Don't cry for Leo, though. Soon he'll be boning another Victoria's Secret model and getting the DiCraprio washed out of him again. He's King of the World!
