In just 24 hours Lady Gaga will release the second single from her forthcoming album, "ARTPOP."

"Do What U Want (Featuring R. Kelly)", the follow-up to lead single "Applause", will drop on Monday morning at 12:01 a.m.

Gaga tweeted the news, along with the racy new artwork for the single, featuring a close-up of her butt in a thong.

"OFFICIAL DO WHAT U WANT FEAT @RKelly COVER ART. Song Available this Monday 12:01am!" Mother Monster tweeted.

Seems like butt-selfies are the new thing. Reality star Kim Kardashian shared an image of hers on Twitter, causing a huge uproar on the internet and getting lots of negative comments from all the haters.

The socialite just wanted to show off the weight loss she accomplished in the past four months since daughter North was born.

Pro surfer Anastasia Ashley then mocked Kim, posting her own derriere in a shot set up in the same style.
