Despite denials from both camps, rumors of hook ups between Rihanna and ex Chris Brown just won't die. The latest tale comes from RadarOnline, whose sources insist the pair are, in fact, meeting up regularly -- but that it won't turn into anything serious.

"They have probably hooked up no more than half a dozen times in the past year," a source told Radar. "It's very unlikely that Rihanna and Chris would ever get back together though." Many speculated that Rihanna's reluctance to reunite with Breezy wasn't because she didn't have feelings for him, but because she feared the public outrage that would ensue if she reunited with her former abuser. However, Radar's sources say that's not the case at all.

"Rihanna doesn't care if she were to get public backlash if they were to reconcile, she is the one calling the shots now, which she likes," the source claimed. "Rihanna knows that if they were to get back together, she wouldn't be able to maintain that strong role, and Chris would lose interest. They are both very young, and Rihanna would never be able to trust Chris because he has problems staying faithful."

Radar also disputed the idea that Karreueche Tran is actually Brown's girlfriend. "[Karreuche] wishes she was Chris' girlfriend! Chris doesn't have a girlfriend right now, period," the source said. "There are many women that he spends time with and she is one of them, it's not an exclusive relationship though." We wonder if she knows that, considering Breezy allegedly got her face tattooed on his arm!

The drama doesn't stop there. Radar says that Brown is a bit of a mama's boy -- and that mama loves RiRi but doesn't like Tran. "Chris' mom, Joyce Hawkins is very leery of Karreuche, and she doesn't like her and questions her motivations and sincerity," a source told Radar. "Complicating matters for Chris is that Joyce loves Rihanna, and she often calls her the daughter she never had but always wanted. Joyce would love for Chris and Rihanna to continue to spend time together, and maybe down the line, get back together.”

Time will tell with these two. Do you think Brown and Rihanna should get back together, or do you think it's a bad idea considering their volatile past? Let us know in the comments!
