Coldplay frontman Chris Martin has laughed off rumours the band is on the verge of splitting, insisting the group will never break up.

Last month, Martin hinted that the band would cease in 2010, adding: "I'm 31 now and I don't think that bands should keep going past 33."

But now he has reassured fans that the Yellow hitmakers still have a lot of music left in them - and are focusing all their energies on their next album.

He tells Rolling Stone magazine, "We're proceeding as if it's our last because it's the only way to proceed.

"You've got to have deadlines, you know. What that means is we're going to pour everything we can into next year and not think beyond that. We always say that and we always mean it. But every time we say it, someone writes that it's over.

"I don't think we'll ever split up but we have to do a lot before we're 33."
