Ke$ha explains on-screen pee drinking

Ke$ha says fans will see her drinking her own pee in the upcoming documentary about her life.

Ke$ha: My Crazy Beautiful Life is scheduled to premiere on MTV in April and will give an insight into the eccentric singer's habits.

The 25-year-old says viewers can expect some strange things from the series, which was filmed by her journalist brother Lagan Sebert.

"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, but it's my little brother and he's my best friend. He's got me wasted at 6am... 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..." she revealed to BBC Radio 1.

"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."

Her outlandish behaviour has won the Tik Tok singer an army of adoring fans.

However, she joked she wishes the people around her on a day-to-day basis would appreciate her more.

"[How often do I get told I'm amazing?] Not enough! My fans are amazing to me but usually the people around me say, 'You're disgusting!' or, 'Put your pants on!' or 'You're late!' Or they say, 'You smell weird, what's that smell?' I smell like a hobo," she admitted.

"One time, someone told me I smelt like a shrimp on a diaper. I thought I could make a fragrance that was little like a shrimp on a Faberge diaper but I don't know if people want to smell like that."

Ke$ha is known for her bold fashion choices as well as her crazy antics.

The star is always covered in glitter and divulged how she achieves her sparkly look.

"Generally, I do glitter twice a day," she revealed.

"I have a bathtub; when I go on tour I bring a bathtub and I have a glitter roadie. His only job is to deal with the glitter and his job is to lather baby oil all over my body. Then I roll around in it and have to sit there until the baby oil dries. When I go to the bathroom you can follow the trail of glitter and tell which stall I peed in. I leave it all over the men I make out with."
