Rihanna, Chris Brown's Song 'Nobodies Business' A Message to Fans?

Rihanna and Chris Brown have collaborated on a new song, and it's the second since reports of a reconciliation emerged. Critics believe that the song acts as confirmation that they have rekindled their relationship.

"Nobodies Business" is the 10th track on the Bajan singer's imminent sixth studio album "Unapologetic," and while she has already set tongues wagging over the deluxe album version's $250 price tag, the tumultuous pair's new song will undoubtedly spark further criticism.

With lyrics like "Me and you, get it / Ain't nobody's business" and "There's no other love just like this ... I sing it to the world," the pair finally appears to be opening up about their controversial relationship.

In August, after months of speculation Rihanna, 24, revealed that both she and Brown, 23, still love each other and spend time together even though at the time he was still involved with 24-year-old model Karrueche Tran. Brown, who split with Rihanna in 2009 following a domestic assault incident, later admitted to ending his relationship with Tran over Rihanna.

"I still love him," Rihanna openly told talk show host Oprah Winfrey. "We're very, very close friends. We built a trust again and that's it. We love each other and we probably always will."

The pair has been spotted spending more time together in recent months and on Sept. 6 they excited fans by openly kissing at the 2012 MTV VMAs. However, not everyone is said to be thrilled about their reunion as new reports suggest that Rihanna's best friend Katy Perry may have ended their friendship over Brown.

Perry reportedly admitted that she has barely spoken to Rihanna since she and Brown got back together.

"We've had dinner, and that's about it, I didn't reach out to her after the incident," Perry recently told MTV. "I think she is doing fine. I don't know. Her personal life has probably already been blown out of proportion. I don't really have to go into that. I'm sure she probably wants a break."

Closer to home however, Rihanna's father has openly supported her reunion with Brown since their 2009 split. He revealed that he would gladly walk his daughter down the aisle if she were to marry Brown.

"Whatever makes her happy. I hope one day she will get married. Everyone adores Chris; he's a super guy," Ronald Fenty previously told Life & Style magazine.

"The family loved Chris Brown before they even met him. I always thought he was extremely talented. He always gave me great respect," he went on.
