Chris Evans has blamed Billie Piper's role in Doctor Who for his break-up with the star.

The DJ has admitted that Billie was unable to spend any time with him while filming for the show, as her schedule was too busy.

Chris told The People, "When she got the job in Doctor Who in Cardiff we were never together. You don't get married to be apart, that's what I say. Are we divorced? No, but we're separated and will be."

However, Evans admits that other factors played a part in their marriage breakdown.

"Did the age difference present a problem? Yes, in the end," he told Q magazine. "I definitely would get married again. What I'd do differently is not get divorced."
