Chris Brown sparks rumors that he has rekindled romance with his ex-girlfriend Rihanna after recently wearing her necklace or at least one that looks very similar to hers on stage. 

While making a guest appearance on "The Tonight Show Starring Jimmy Fallon" on Sept. 12, the R&B star performed the title track off his just released sixth studio album "X," as well as his summer hit "Loyal."

MediaTakeOut.com first pointed out that Breezy was wearing a gold chain with an angel hanging off it - the same one that RiRi has and was previously photographed wearing it in a black-and-white snapshot.

Amid "hearing rumors for weeks that Chris Brown and Rihanna were on the verge of getting back together," a source revealed to the website that the pair has been in contact all along. "Rihanna and Chris never stopped talking," the source told the website. "They were supposedly 'just friends' but they would always flirt. There is a real 'soul mate' connection between them."

Despite their highly publicized breakup and drama, the "Drunk Texting" crooner and the "Stay" singer apparently have a complicated yet strong bond. "They have a bond and connection that's so deep that no one can fully understand except them," another source claimed to Hollywood Life. "That's just a fact. He knows it. She knows it. Everybody knows it and that's that."

"When it comes to Rihanna, you know, her name and his name will forever be intertwined, no matter who she's talking to at any given moment," the source added.
