Sources are again suggesting that Gwyneth Paltrow's marriage to Coldplay rocker Chris Martin is on the rocks -- but new reports say actress Kate Botsworth is to blame. Insiders told X17Online.com that Martin and Botsworth were spotted making out in two separate public locations over the past few weeks.

A source told the website, "Chris is totally Kate's type, she loves the Brits like Orlando and James Rousseau. And she's Chris' type, too. A blonde bore, just like Gwyneth!"

Martin's rep is denying the story however, telling, Usmagazine.com: "This story is entirely untrue." Another source added that the he and Paltrow are "more than fine."
