Harry and his Twitter followers were all in for a bootylicious treat with a hilarious photo of the 1D member's bum. And it seems that Harry wasn't the only one who had bare "belfies" aka butt selfies to share.

Sugarscape reports that the hilarious vintage photo of Harry's behind has been the talk of town ever since it got out online over the weekend.

The 1D member appears to be taking a piss by the bush with trousers dropped to his knees. And since Harry naturally had his back against the camera, his bum was rightfully exposed for everyone to see.

Harry Styles (@Harry_Styles) recently tweeted "Mix-A-Lot's in trouble," which had a few fans confused.

One fan, harriet ‏@luxunarry, tweets, "@freespiritlouis @louisbubble waittt i dont get could you please explain it to me?" 

Another fan said that Harry's tweet was actually with regards to his bum-showing photo that has made its way online.

carls ‏@freespiritlouis clarifies, "@luxunarry the song baby got back which is about big butts is by sir mix a lot & the picture of Harry's butt was going around."

A Twitter account dedicated to Harry's butt has also recently been created - Queen of Ass (@harryswhiteass), which has gained a couple of thousand Twitter followers since its creation.

And based on the photos uploaded by the user, it is dead serious on making Harry's "white ass" known to the world - or at least have a piece on the social networking site.

One photo uploaded by Queen of Ass @harryswhiteass features Harry in the recording studio with pants dropped dangerously low while Zayn stands by his back. The user captioned the picture-worthy moment, "Zayn wants a piece of this booty."

HYFR @1DScoop also compiled butt shots of 1D members Harry, Niall and Louis, captioning the photo, "LIAM AND ZAYN I AM WAITING."

Butt talks aside, One Direction kick starts 'Where We Are' world tour June 1 at the Manchester Etihad Stadium, according to the tour's webpage. The boys will be taking their music across the UK, Ireland, Latin America and the US in the coming months.
