A rep for Coldplay star Chris Martin has dismissed speculation that he had an affair whilst married to Gwyneth Paltrow.

The celebrities, who have two children together, announced recently that they would be splitting after ten years of marriage.

New reports have emerged that suggest the musician had an affair with a TV assistant in 2011.

The rumours claim that Martin met the woman backstage at Saturday Night Live.

However, a rep for the Coldplay man said in a statement: "This is completely untrue, we totally deny it."

The couple's split statement meanwhile, which was uploaded online on March 25, read:

"It is with hearts full of sadness that we have decided to separate. We have been working hard for well over a year, some of it together, some of it separated, to see what might have been possible between us, and we have come to the conclusion that while we love each other very much we will remain separate.

"We are, however, and always will be a family, and in many ways we are closer than we have ever been. We are parents first and foremost, to two incredibly wonderful children and we ask for their and our space and privacy to be respected at this difficult time. We have always conducted our relationship privately, and we hope that as we consciously uncouple and coparent, we will be able to continue in the same manner."
