One Direction hired a luxury £2.3million yacht to escape their fans onshore in Miami, so the boys can be forgiven for letting their guard down.
But clean-cut popstar Louis Tomlinson has caused a stir after he was seen holding a weird looking cigarette.
It could be one of those foreign types with white filters or just a prank-fag from the joke shop... the mystery remains.
Louis, 21, is seen holding the funny fag while Zayn Malik appears to be shielding the wind around his mouth.
Another ciggie can be seen on the table as One Direction fans discussed the pictures on Twitter.
The pictures have certainly sparked interest online as fans pondered over what their idols were chugging into their lungs.
One person wrote: “I hope Louis smoking is a one in a million thing and also I hope it's not pot.”
While another wrote: “Who cares if Louis and Zayn are smoking weed? It’s their life and everyone grows up and tries things.”
A spokesperson for One Direction declined to comment.
