Gwyneth Paltrow's Mom Blythe Danner "Really Upset" Over Chris Martin Split

It sounds like Gwyneth Paltrow's mom Blythe Danner is more bummed about her daughter's separation from Chris Martin than anyone else -- including Gwyneth!

"[Blythe is] really upset. She loves Chris," an insider tells Us Weekly. "She begged Gwyneth not to end it, that he's a good man. But Gwyneth had to do what she felt was best."

Danner and Paltrow's father Bruce were married for 33 years until his death in 2002, and back in June of 2013, Paltrow chatted with Glamour about how her parents made things work. "I asked my dad once, 'How did you and Mom stay married for 33 years?' And he said, 'Well, we never wanted to get divorced at the same time.' I think that's what happens. When two people throw in the towel at the same time, then you break up, but if one person's saying, 'Come on, we can do this,' you carry on." Talk about foreshadowing....

"[Gwyneth and Chris] really tried to make it work," Us mag's source continued. "You could tell something was wrong, though, over the last few months. You could see a sadness in each of their eyes."

Or could you? There's a new report in the Sun that Gwynnie is on the rebound, which would certainly indicate that there's zero chance of a reconciliation. The tabloid reports that the Oscar winner is "ready to have another boyfriend ... She's very much about having fun."

Guess we'll have to see that to believe it!
