Ke$ha is all about being crazy and spontaneous, but she took it to a whole new level Tuesday night on her MTV reality show.

Ke$ha is known for doing some crazy things, but Tuesday night’s episode of her MTV reality series Ke$ha: My Crazy Beautiful Life takes the cake.

During the episode, the 26-year-old singer talks about her desire to look hot for an upcoming music video shoot.

“Now it’s time to switch gears, because I have a music video to make,” she said. “I want to get in kick-a** shape and look damn hot, and I’ll try just about anything.”

And she wasn’t kidding: She peed into a bottle — and drank it — after one of her companions told her about a hiker who drinks her own waste “like every day.”

“I’ll drink my pee,” she said. “I’ll totally drink it.”

Cameras panned away as K-E-dollar sign peed into a plastic bottle. It’s supposedly legit because MTV included the sound effects.

“It doesn’t even smell that bad,” Ke$ha said as she took a whiff of her own brand. “Here, smell it.”

Luckily, her friends declined.

So, did it help her magically lose weight and get hot? Nope.

“I heard it was good for you. That was, like, the rumor,” she told E! News at the 2013 MTV Movie Awards. “But I don’t know. I’m also just one that doesn’t shy away from things. I’m not good at saying ‘no’ so I just figure, f*** it, I’ll try anything once.”

Plus, it tasted nasty (imagine that!).

“I wouldn’t recommend it. It was pretty gross. And I don’t think it really did anything very beneficial to me so, yeah, I wouldn’t probably do it again,” she added.

So, take it from Ke$ha: Don’t drink your pee unless you like to drink really gross things on a regular basis.
