Singer Rihanna arrives for the Council of Fashion Designers of America Awards (CFDA) at Lincoln Center in New YorkReuters

Rihanna, 26, seems to be happy about her ex-boyfriend Chris Brown's break up with Karrueche Tran, 25. It is reported that she was not surprised by Brown-Tran break-up and is glad that she is not pulled into the split drama.

"She's not trying to be a b**ch but her attitude towards it is like what goes around comes around," a source close to Rihanna told Hollywoodlife, adding, "She's just glad she's not on the receiving end, again, off his bulls**t. Better that girl than Rihanna."

Rihanna reunited with Brown despite the latter was charged for physically assaulting the "Diamonds" singer but broke again in May, 2013 after months of speculations. It was reported that RiRi wanted to start a family with Brown but the latter was not interested.

"When my girl tell you she loves you and wants to be serious with you and start a real life with you and maybe even have your baby in the future, you turn her down, and then put her on blast on a radio show.That's all bad. Like game over," told a source to Hollywood Life.

"It's that one piece that's missing, but it's cool because she's not looking for it," the source added. "She's over searching. She knows it will come, that he will come. And when he does, it's going to be a real tight fit, in every way possible."

Rihanna had also been linked to rapper Drake earlier this year. The two were seen hanging out in public together on many occasions but their romance fizzled out in no time as Drake called Rihanna "needy", according to reports.

Meanwhile, Brown and Tran had on-again off-again romance for one year. It was reported when Brown was in jail that he would commit to Tran for marriage. The buzz has it the couple was even ready to move in together but things didn't seem to work out.

Currently, Brown is busy with his musical career whereas Tran is working hard on her blossoming fashion career.
