One Direction has made music history!

The British/Irish boy band's first album, Up All Night, debuted at the number one spot on the U.S. Billboard chart Wednesday, making them the first UK pop group to do so!

Up All Night was previously released in the UK in November and debuted at number two. Meanwhile, their debut hit, "What Makes You Beautiful," has been dominating the airwaves and even won a Brit Award this year for Best British Single.

It’s been quite the year so far for band members Niall Horan, 18, Zayn Malik, 19, Liam Payne, 18, Harry Styles, 18, and Louis Tomlinson, 20, who got their big break when they placed third on Simon Cowell's British X Factor in 2010.

Their record-breaking news comes a week after Nickelodeon confirmed via the network's official Twitter account that the boys would be making their TV debut.

"The rumors are true, our live-action slate does include a development project for One Direction. Welcome to the family!" the network tweeted March 14.
