"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?In 2009, Chris Brown was arrested for felony battery on Rihanna, the night before the Grammy Awards. Now they're making beautiful music together again.
Only in the literal sense ... or maybe not. While sources say they are not planning a reconciliation, Rihanna would not fear the public backlash if they did.
"They have probably hooked up half a dozen times in the past year, but it's unlikely that Rihanna and Chris would ever get back together though,” an insider said.
The reason being?
“Rihanna doesn't give a s--t if she were to get public backlash if they were to reconcile, but she is the one calling the shots now, which she likes."
"She knows that if they were to get back together, she wouldn't be able to maintain that strong role, and Chris would likely lose interest."
"They are both very young still, and Rihanna knows she would never be able to trust Chris because he has problems staying faithful."
Given that he's supposedly hooking up with her while dating Karreuche Tran right now, she would have a decent argument to make there.
