Louis Tomlinson and Zayn Malik have been photographed on board a yacht off the coast of Miami with a funny looking roll-up.
The unusually shaped cigarette has caused a stir with fans who are worrying about One Direction's smoking habits.
In a photo, a mysterious fag can be seen on the table next to Louis, 21, while Zayn, 20, appears to have one of his own that he's trying to light.
The roll-up could've been a fake cigarette from a joke shop - it's a mystery - but unsurprisingly, Twitter was abuzz with reactions from 1D fans.
One wrote: “I hope Louis smoking is a one in a million thing and also I hope it's not pot.”
There is no evidence the boys were smoking anything other than tobacco, but Directioners were quick to compare Louis and Zayn to Justin Bieber.
Canadian singer Justin hit the headlines recently when he was snapped smoking what looked like a joint.
One fan wrote: "Justin smoked weed and his fans started to cut for him zouis did and we're laughing god bless the one direction fandom."
A spokesperson for One Direction declined to comment.
The lads are in Miami for the next leg of their Take Me Home tour and had been enjoying the sunshine on the £1.5million yacht before their first performance.
They wowed their adoring fans by going topless and Harry showed off his latest tatt.
