There must be something in the air! So many cheating scandals lately!

Chris Martin, Coldplay frontman and Gwyneth Paltrow's husband, was reportedly seen making out with a blonde that wasn't his wife!

Eyewitnesses are claiming that he was kissing actress Kate Bosworth, who has been recently romantically linked to True Blood's Alexander Skarsgard.

A witness says:

"I couldn't believe my eyes. There was Chris totally making out with Kate in front of other people. At first I thought it might be Gwyneth, but when she came up for air, it was clear the woman was Kate!"

Sounds like Gwynnie's perfect marriage could be on the rocks!
