Justin Bieber has lavished praise on Taylor Swift, calling her "great" and "so talented".

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"
