Karrueche Tran Wins, Chris Brown Instagram Love 'Infuriates' Rihanna? Girlfriend Prompts 'Beef' With Sexy Couple PHOTOS

Although hip-hop superstar Chris Brown's officially moved-on with current girlfriend Karrueche Tran, ex-lover Rihanna still remains single (after several failed relationship attempts with YMCMB rapper, Drake). Is 26-year-old Tran worried that RiRi might try stealing her man back? Well, apparently not!

Rumors suggest that the aspiring model and 26-year-old "Diamonds" beauty will never get along as friends - which really comes as no big surprise. They'll always be in competition with one another, and right now, Tran's winning!

According to an alleged insider for the popular gossip webloid UrbanIslandz.com, Trans enjoys getting under Rihanna's skin and making her jealous:

"They both are jealous of each other but this time Karrueche is winning because she got the man both of them want."

The source continued, "K is rubbing it in RiRi's face and on Instagram everyday and RiRi is watching better believe that."

But does the Barbadian beauty even really care? She's busy promoting her own name and brand on Instagram... no time for boy drama, here!

And she still looks as gorgeous as ever, should Tran have something to worry about when it comes to Breezy's wandering eye?

Maybe not - the couple looks extremely happy and content... dare we even say "loyal!"

Should fans finally forget about Chrianna, and just accept Brown's new sweetheart? Apparently he recently purchased the exotic beauty a high-end house rental in LA, so things are definitely getting serious!
