Rihanna and Chris Brown are apparently going through a rough patch. Again.

Star magazine claims that "sources" revealed that Rih-Rih threatened to "kill" Chris if he dumps her for his (other) ex, Karrueche Tran. And apparently, Breezy got in line after she made the threat.

“Rihanna has said that she’ll ‘finish Chris off’ if he dumps her again. She says she’s been through so much pain to get Chris back that his life won’t be worth living if he breaks her heart again,” explains an insider. “Chris has told her that he wants to marry her and be with her forever.”

“It’s pretty scary — but instead of freaking Chris out, it seems to turn him on,” they also claimed.

Doesn't sound like a very likely story. But you never know.
