Chris Martin's rep is denying a new Star tabloid story that claims the Coldplay rocker, 32, recently kissed 26-year-old actress Kate Bosworth.
Star quotes an unnamed as saying that Martin was "totally making out with Kate in front of other people" at an unnamed event.
But Martin's rep tells Usmagazine.com: "This story is entirely untrue."
Martin and his wife of six years, Gwyneth Paltrow, are "more than fine," a source tells Us.

The source says the alleged Martin-Bosworth make-out "simply never happened.
She may have been in the same room with him, but he is not having an affair, was not kissing her or holding her hand."
