Clean-living Liam Payne and Niall Horan return to the recording studio... after new photos emerge of 1D bandmate Louis Tomlinson with a suspicious 'cigarette'

It seems like another day, another drama for the One Direction boys, but on Friday, while Louis Tomlinson was spotted with a suspicious looking cigarette, bandmates Liam Payne and Niall Horan were showing themselves to be consummate professionals.

The two singers were spotted heading to a recording studio in west London, just hours after having made an early-morning exit following hours of dedicated work on their anticipated new music.

They were casually dressed for their second consecutive day of work, with Liam donning a black longline T-shirt with matching skinny jeans and Niall stepping out in a grey newsboy cap with a green jacket and jeans.

Hours earlier, during their Thursday night session, Niall posted a snap to his Instagram of himself with songwriter and producer Julian Bulian simply saying, 'Hat , headphones and glasses boiissss'.

The pair were working hard into the night in the recording studio with fellow 1D member Liam.

Meanwhile, Louis was spotted going on a wild night out to Cirque Du Soir nightclub in London, and later returning to his hotel room with a group of at least five girls.

Photographs have since emerged of Louis with a suspicious cigarette and a container of green herb-like substances.

The snaps were allegedly taken on Wednesday amid 48 hours of hard partying from the oldest member of the band.

The 23-year-old has been enjoying the night life recently since breaking up with his then-girlfriend Eleanor Calder last month.

Louis' behaviour is the latest blow to the band after Zayn Malik's recent decision to leave the band. 

Back in March he declared that he was quitting One Direction in an effort to live the life of a normal 22-year-old.

It appears Liam and Niall are happy to continue their life in the band and show no signs of going off the rails.
