Coldplay: 'We're too old for a Justin Bieber duet'

Following the current chart success of their Rihanna duet 'Princess Of China', Coldplay have revealed they have no plans for further pop collaborations - least of all with Justin Bieber.

Frontman Chris Martin has said that he and his Coldplay bandmates are too old to work with the 'Boyfriend' star and that they would look like his grandparents should they ever record a video together.

"Justin Bieber is too handsome for us. If he wants to do a video with four people who look like his grandparents then we should be in it," said Martin in an interview with The Sun. "But we've got to look good — we'd just look terrible next to that guy. He's good-looking and has an amazing complexion."

Has also spoke highly of his time working with Rihanna.

"Rihanna was top of our list of collaborators, and we've done that," he said. "She was lovely — she was cool. We'd work with anyone who wanted to work with us.
