According to a source close to 71-year-old, Blythe supported her daughter's decision but has been left saddened by the couple's separation after growing close to Chris during their decade-long marriage.
"[Blythe's] really upset," a source told Us Weekly. "She loves Chris and she begged Gwyneth not to end it, that he's a good man. But Gwyneth had to do what she felt was best."

Gwyneth, 41, has previously spoken about how Blythe's union with her father Bruce Paltrow helped her understand marriage.
The mother-of-two recalls how she once asked Bruce "How did you and Mom stay married for 33 years?" to which he replied, "Well, we never wanted to get divorced at the same time."
"I think that's what happens," added Gwyneth. "'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."
