British rocker Chris Martin has denied a report suggesting he cheated on his wife Gwyneth Paltrow with a Tv assistant.

The Coldplay frontman split from the Oscar-winning actress last month (Mar14) after 10 years of marriage but apart from a statement announcing the split, neither star has spoken publicly about the break-up.

However, a spokesman for Martin has now addressed a U.S. media report which alleged the rocker had an affair, telling Britain's Daily Mirror newspaper, "This is completely untrue, we totally deny it."
