Rihanna Doesn't Care About Drake And Chris Brown's Relationships, Karrueche Tran Has No Worries?

Singer Rihanna doesn't care who rapper Drake hooks up with and his infatuation with label mate Nicki Minaj.

According to Hollyoodlife.com, sources say the "Numb" singer is literally numb to the Toronto native's love life.

"Rihanna is numb to men at this point. She doesn't understand them and is rather tired of trying to. She'd rather stay single and alone in her bed before giving it up and exposing her heart to more disappointment. Her exes are her exes and they're that for a reason."

The source added, "She's can't concern herself with who Drake sleeps with these days. She's over him. She's over Chris as far as anything sexual goes."

While her ex-boyfriend, Chris Brown is moving along with Karrueche Tran, the international pop star hopes that she can move on with any thoughts of her past boyfriends concern, "Belong to other women now and she wants the best for the both of them. But in no way does she care at all about who they're sleeping with these days and she would hope they wouldn't care who she's with," explains the source.
