A photo that's allegedly of One Direction cutie Harry Styles' bare butt has surface online, featuring the singer without pants and peeing into some bushes.

The undated photo was shared on Twitter by a One Direction fan site, and it prompted Styles to send an interesting tweet to rapper Sir Mix-A-Lot, referencing his nostalgia-inducing song 'Baby Got Back.'

Which prompted the rapper to ask the question on everyone's mind, "Who's bushes you peeing in? Classic!!!"

He continued joking, writing in 140 characters or less:

For his part, Mix-A-Lot says he didn't release the photo and that he doesn't even know Harry.
