Singer Lionel Richie has been forced to postpone a tour with Mariah Carey after a knee operation.

The 67-year-old singer said their All The Hits Tour will be postponed until the summer. The 35-date tour was supposed to launch in the US on March 15 and end on May 27.

Richie said: "Unfortunately my recovery from a knee procedure will not have me 100% ready to start the tour."

He said he does not want to disappoint his fans and he's looking "forward to being back onstage so we can all be 'Dancing on the Ceiling' together again".
