Ke$ha has never been shy and yesterday she took her openness to a whole new level by peeing on the street and tweeting a photo of it!

Yesterday, Ke$ha apparently got stuck in traffic and just couldn't hold her bladder any longer, so she decided to pop a squat in the street and handle her business.

Pee pee on the street. PoPo come and get me if you can find me, Ke$ha tweeted. I blame traffic.

In the picture you can barely see Ke$ha's face, but she is wearing a pink hoodie and black pants, which are partially pulled down.

If Ke$ha would have been caught in the act, she could have been fined $270.

Ke$ha has a history of urinating in public places. In 2010, at the Brit Awards, her and Lily Allen met while peeing in a sink!

Lily Allen is a total sweetheart, Ke$ha said. We met when we were both peeing into a sink at the BRITs a few years ago.

And it seems that Ke$ha has a sense of humor about her wacky antics.

I'm just very amused by five-year-old humour, Ke$ha said. But who isn't amused by a giant, dancing penis? Sometimes when I'm sad, I make my assistant put on the penis outfit and bounce around my house.

Ke$ha is known for her wacky fashion, party lyrics in her songs and over-the-top makeup and now she can public urinator to the list.
