Ever since Gwyneth Paltrow and Chris Martin broke the news of their divorce - sorry, conscious uncoupling - yesterday, rumors have been flying about why.
Most have revolved around Gwyneth, who had to deny she was having an affair with Elle Macpherson's billionaire husband, Jeff Soffer, in 2013.
As recently as last month, her rep denied that Paltrow cheated with entertainment lawyer Kevin Yorn ... and she was seen kissing Donovan Leitch.
But what about Martin's role in all this? According to a new report, it may have been his affairs that led to the uncoupling: Specifically with Alexa Chung.
Supposedly, the two shared an open marriage, with neither getting into anything serious. Until Chris got involved with Alexa Chung, and got VERY serious.
The fashion It Girl and Coldplay singer developed feelings for each other at the Glastonbury Music Festival in June of 2013, new intel suggests.
They were seen wandering the festival site together, posing separately for photos with a fan who remarked on Twitter that they were "both so lovely."
They were seen together multiple other times that weekend.
Whatever the reason, it is certainly sad and surprising that Gwyneth Paltrow and Chris Martin split after over 10 years together and two children.
Why they chose to take a sad, private life change and make it comical with their "conscious uncoupling" mumbo jumbo that only invited increased speculation?
That part is beyond us, but it's also Gwyneth Paltrow to a T.
