“Julia was at Gwyneth’s engagement party but missed her wedding and then showed up at the party Chris and Dakota Johnson were throwing instead," dished the snitch.
As readers know, Roberts was one of the celebrity guests at the couple's star-studded bash celebrating Johnson's 29th birthday.
But the Goop guru wasn't happy with Roberts attendance. The duo go way back, but sources tell Radar exclusively the Pretty Woman actress also befriended Chris during their marriage and now "she’s taking sides and has decided she’s on his."
"Gwyneth and Chris stayed friendly after their divorce but things have changed and it’s been difficult for their mutual pals to stay friends with them both," spilled the snitch.
"Gwyneth isn’t Dakota’s biggest fan and Brad Falchuk didn’t want Chris at their wedding celebrations, so Gwyneth isn’t happy to see Julia hanging out with her ex.”
