One Direction star Niall Horan has opened up on a wild night at the casino that left their management fuming.

Like a lot of British lads, the boyband decided to celebrate an 18th birthday in style by hitting a casino.

However, it ended up with some of the singers losing wads of cash as their gambling inexperience showed through. Horan told We Love Pop:

"I won £100, which seemed reasonable, then I stopped. But I'll have to say 'No comment' about the others."

He continued: "Let's just say it got a bit ugly and a lot of money was lost. A lot. When our management found out, we got a serious dressing-down about it."
