"Girl I wanna f*** you right now. Been a long time, I've been missing your body." - the first line of Chris Brown and Rihanna's remix of "Birthday Cake"
Despite suggestive lyrics like that, and plenty of other rumors surrounding Chris Brown and Rihanna, Karrueche Tran isn't bothered by all the noise.
That's because the two have an open relationship, according to reports.
"Karrueche isn't stupid, and she has told friends that they have an open relationship. She never asks about Rihanna, ever," says a source of Brown's girlfriend.
"Chris will take several days to call her back at times, and that is OK with Karreuche. She doesn't pressure or hound Chris, it's just not what she is about."
"She recognizes that they are both young, and she isn't going to let the fact Chris is spending time with his ex-girlfriend come between what they have."
What they have? It doesn't sound like much ... but good for them!
Karreuche and Brown were recently seen in Miami, and she "is clearly enjoying the attention and notoriety she is getting being his girlfriend," a source says.
As for rumors that Rihanna may become his girlfriend instead?
