louis  tomlinson Shows Off His Driving Skills As He Gives Zayn Malik A Lift In Behind-The-Scenes Video (WATCH)

The 1D star is quite impressed with his new Vine skills!

Those One Direction boys are always joking around backstage and Harry Styles has shared yet another Vine video with his millions of followers, as he posted the clip of the band messing around in a forklift truck during one of their tour dates.

In the short video, Hazza can be seen taking the wheel of the vehicle as Zayn sits on the back, whilst they whizz around backstage at a venue.

The Vine video is just one of the latest in Harry's behind-the-scenes clips that he shares on Twitter - we wouldn't mind a lift on the back of his truck next time!

Meanwhile, the 1D boys opened up about the curly haired cuties' partying ways in a recent interview with the Daily Star, claiming that Harry joined a group of students in Norway on their party bus whilst they celebrated their graduation.

Liam, 19, told the newspaper: "You should have seen him. At 12.15 the next day he was just lying there, knocked out, naked on the floor of his hotel."

A red faced Harry, who reportedly found out about the party from a fan staying at the same hotel in Oslo didn't appear too upset by his epic hangover.

Describing the night he said: "It was fantastic. I was in that bus for three hours. It was the best time ever. As soon as I got on board I got three beers poured over me."

Though denying things got out of hand he insisted: "I did behave."

We're not too sure about that Harry as according to a source close to the boys the 19 year-old got close to a pretty blonde called Camilla and has even carried on the romance when the bus party rolled on without him.

“Harry was overjoyed to get the invite to jump on the bus with screaming fans," a source told The Sun.

“There were loads of girls pawing him, but he focused on Camilla. It got pretty sweaty in there.”
