Kanye doesn't use phones - Justin Bieber

Kanye West doesn't use phones, according to Justin Bieber.

The rapper and the pop star worked together on a remix of his track Runaway Love, which will be included on Justin's new LP Never Say Never - The Remixes, but the 16-year-old singer insists the creative process was made harder due to Kanye's reluctance to speak on any telephone.

He said: "It's funny, because he doesn't even use a phone, he just sends email. It's so crazy. I'm like, 'How can you not use a phone?'"

Despite his aversion to telephone chats, Justin insists it was great working with Kanye because he was such a talented and "nice" guy to be around.

He added to MTV News: "He reproduced the Runaway ... joint, and I'm really excited.

"It was amazing. He's such a cool guy, and he's just really laid back and just nice, and at the end of the day, he's just a nice person."

Meanwhile, Justin's manager Scooter Braun has revealed the 16-year-old music sensation has been working with Kanye, 33, on several tracks which could make his next studio LP.

Scooter said: "Justin is working on new music. He and Kanye had a call the other day about a song they're trying to work on together - Kanye wants to produce a bunch of new songs for the new album."
