Teen sensation Justin Bieber's spokesperson has slashed rumors of the singer collaborating with British band One Direction for an upcoming album Believe.

They just came by the studio and heard some of the album Believe, the rep told GossipCop.

Speculations on the same started when the group visited the 18-year-old Boyfriend singer during a studio session Tuesday.

Also, singer Niall Horan tweeted and told his fans a day later that it's gona sound great.

In the studio with our boy Justin Bieber last night, it's gona (sic) sound great! Contactmusic quoted him as tweeting.

The tweet started rumors of the What Makes You Beautiful singers working on a song for Bieber's upcoming album.

Meanwhile, Justin Bieber has made the highest Billboard debut again with his latest track Boyfriend Wednesday grabbing the No. 2 position on the Billboard Hot 100 singles chart.

The Canadian pop singer's new single with an amazingly nice beat, an obviously mature voice and rapping talent, has made its way into millions of hearts.

Love him or hate him, Justin Bieber is undoubtedly going great guns!
