When in Latin America...celebrities get wild!

Louis Tomlinson and Zayn Malik, two members of the popular boy band One Direction, apparently let (very) loose while on tour in Peru.

A video -- which appears to have been taken with Tomlinson's phone -- leaked on Tuesday and was streamed exclusively on The Daily Mail's site.

Malik is seen lighting a marijuana joint while wearing a Bob Marley tank top. "So here we are, leaving Peru. Joint lit. Happy days!" Tomlinson can be heard saying as he films his bandmate.

“Zayn takes his job very seriously,” Tomlinson said. “He makes sure he goes through a two hour intense warm-up before every show.”

“One very, very important factor of Zayn’s warm-up of course is Mary J herself,” he continued.” In fact I will present it to him now for some fantastic singing.”

Malik is seen taking a few puffs before blowing smoke into the camera and passing the joint on to Tomlinson.

The video has reportedly shocked and angered millions of fans, and according to The Daily Mail, this could ruin the band's clean image.
