Kesha

Pop music's beloved raunchy girl Kesha has entered rehab.

Glitter covered, pee drinking, teeth wearing, ghost-sexing singer Kesha is known for her big, bold style and her love of wild hair colors, and she may have just dyed her hair our favorite shade yet: rainbow.

She may have a reputation as one of the dirtiest girls in pop, but party-happy Kesha is actually a bit of a clean freak. But rest assured, she's still a freak, which she embraces, and that's what we love about her.

Kesha really is a party animal. The whiskey-swigging, critter loving cutie revealed a secret about herself -- and goodness knows she doesn't keep too many of those to herself. The 'Supernatural' singer was actually born with a tail. Oh, and her pee is delicious. Yes, you read all that correctly.

Teeth. They're not just for chewing anymore! The always fashionably unconventional Kesha is showing her teeth … sort of. Her new jewelry line, Kesha Rose by Charles Albert, will feature actual teeth. It's not a shock, since the singer once wore a head piece constructed of fan's chompers. With Kesha, dentition is merely a means with which to accessorize!

Kesha is ghetto fab in her 'Crazy Kids' video. Wearing cornrows, lots of bling, dagger nails and garter belts with shorts, the singer cruises through a late afternoon house party like it was the most normal thing in the world.

Kesha gave fans a taste of her new, unreleased track 'Machine Gun Love' on her show, 'My Crazy Beautiful Life' -- and then she let them hear it live!

Kesha made some headlines late last year when what appeared to be a photo of her performing fellatio ended up on Twitter. At first, we chalked it up to another outrageous Kesha moment, which the 'Crazy Kids' singer is prone to having. But she has revealed that she was so depressed when that photo came out that she contemplated suicide.

Kesha channeled uber nerd Urkel and James Franco's nefarious character Alien in 'Spring Breakers' with her attire on the set of her 'Crazy Kids' video.

Kesha is a handful and we think she gave Conan O'Brien all he could handle as a guest on his TBS show.
