Just read this on my favorite gossip website:
"Gwyneth is extremely cool at work. She's just a step above professional, too snobby. Gwyneth is not friendly to anyone, and tends to make people feel awkward and uncomfortable. She wasn't outright rude to Scarlett, she just didn't ever speak to her. Gwyneth went out of her way to avoid Scarlett, and they had zero contact, at Gwyneth's choosing."
The crew does love Chris:
"Much of the crew didn't mind hanging out with her husband, Chris, but if Gwyneth ever came around, they scattered! Chris is so chill and relaxed and she is just the opposite. Chris has been a crew favorite since the filming of the first movie."
