When writer and professional Twitter troll Jenny Johnson provoked notorious hothead Chris Brown into a Twitter war, he had an unlikely defender: ex girlfriend Karrueche Tran.

Karrueche's pals told Hollywood Life that the model thought Johnson's messages were "rude" and that she should "shut up." No argument there, but what about Breezy's unflattering -- to himself and to Johnson -- responses?

“That s--- was funny and kudos to Chris for calling her out,” a source said Karrueche told them. “Who is [Jenny] anyway? ... She was hella rude for coming at him foul like that and then she was surprised when he came at her hard. She should just shut up! Now look what she made him do — he got off Twitter and now his fans are pissed and deprived.”

Though Tran was pretty humiliated when Brown publicly announced their split, sources say they still talk, text and send each other photos often. “They talked and he did wish her a Happy Thanksgiving and they’ve been sending pics back and forth," a source said. "She’s not tripping on Rihanna being out there with Chris, she’s happy for him and has his back when he gets home."
