Ke$ha posted Instagram photos of her butt on Wednesday. The "Crazy Kids" singer bared her body part in skimpy underwear on the social site. 

According to Hollywood Life, the racy performer went back to her old skin-baring days with the image showing her behind in the air.

The 26-year-old songbird was seen on all fours, wearing a ripped t-shirt, stockings and high heels. She captioned the photo, "Butt."  

It looks like KeSha took a page from Rihanna and Miley Cyrus' book, and intentionally had a wardrobe malfunction. She even posed in a super-risque way, flaunting her butt for everyone to see. 

The photos suggest either the  "We R Who We R" singer was filming a sexy new music video or she likes to strip in her spare time, HL reported.

The singer posed in just a bra covered with glitter in one photo. This photo was just as shocking and jaw-dropping as another image, where the rainbow-colored performer spread her legs in a pair of booty shorts.

And in another photo, the singer was laying on her stomach and showing off her rear end again.

Ke$ha is known for pushing the envelope. The singer was under fire for drinking her own urine on her MTV reality TV show, "Ke$ha: My Crazy Beautiful Life," in May. For our story on the singer drinking her own urine, click HERE.

It seems that pop singers such as Ke$ha are "trying to prove they are in complete control of who they are, but the message may be getting lost in the G-strings," reported HL's Andrew Gruttadaro.
