In Ke$ha's new MTV doc that debuts in April... she admits to drinking her own PEE.  Barf barf barf barf barf barf.  What she says about her documentary:

"It's my brother and his weird friend following me around for the past two-and-a-half years. We didn't know what we were doing per se…

He got all the things you would want to see and all the things you wouldn't really want to see - making out with dudes, drinking my own pee, jumping out of a building, jumping out of aeroplanes, swimming with sharks…"

Then she tried to rationalize what only Tom Hanks would do on an island while chatting up a volleyball...

"I was told drinking my own pee was good, I was trying to be healthy…

Somebody tried to take my pee away from me and I said, 'That is mine!' So I snatched it up and took a chug and it was really gross so I don't do it anymore."
