Justin Bieber has revealed his love for One Direction, and now the singer has confessed that he knows one of the world's "biggest artists" who fancies Harry Styles but he won't reveal who.
The 'Boyfriend' singer reckons that the 1D boys are going to "have a lot of fun" with the girls in the US because the fans will go "crazy" for them.
According to the Daily Mirror, Bieber has insisted that he's "sworn to secrecy" over the identity of the star who has got the hots for Harry.
"I already know one of the biggest artists in the world thinks Harry is so hot, but I have been sworn to secrecy."
One Direction managed to bag a number one with their debut album Up All Night as they supported Big Time Rush and Bieber reckons that by the end of 2012, One Direction will be the world's biggest boyband.
"The single guys from One Direction are going to have a lot of fun," he said. "They look great, they sound great and, when you add their British accents into the mix, the American girls are going crazy for them."
Bieber, who is dating Selena Gomez, continued: "Sure you need the talent, but you need to win over the American public, that's what it is all about. One Direction are genuine good guys.
"The industry needs a fresh boy band, and by the end of this year they will be the biggest boy band in the world."
Well that's news to The Wanted, who are meant to be Justin's biggest pals - think Bieber might have put his foot in it here!
