The Canadian popstar spoke to Capital FM about Swift, who he has collaborated with recently.

Bieber had previously confirmed that he had been working with the country pop maestro - but it was left unclear as to whether their work would make Bieber's forthcoming album 'Believe'.

However, he has now confirmed that the pair have worked on a "couple of things". He said:

"I think so. We're still working it out right now. We worked together on a couple of things so we're just figuring out what we can use. It was great, she's so talented – a great singer-songwriter."

Bieber meanwhile took to Twitter today (April 26) to update fans on his touring plans - proclaiming that he is going to go "all around the world". He tweeted:

"Planning trips for ALL AROUND THE WORLD for #BELIEVE - see u all soon! I LOVE U. THANKS"
