Rihanna has already announced that the title of her upcoming album is Unapologetic.

Now, the star singer is confirming that she and ex-boyfriend Chris Brown have collaborated on a song for the album titled Nobodies Business. (Yes, that's how she spelled "nobodies.")

So there.

As Reuters notes, the song is part of an official track list Rihanna tweeted on Monday after weeks of buzz that the two stars are dating again, and three years after Brown was charged with assaulting Rihanna.

She tweeted on Monday: "Man my album is complete, and I need a (expletive) drink and a roll up! It was quite the journey, but it's all part of our story!#UNAPOLOGETIC"

Brown, 23, is currently halfway through his five-year probation after pleading guilty to assaulting his girlfriend on the eve of the Grammy awards in 2009. He was ordered to complete community service and a domestic violence program.

At a hearing Thursday, Brown was ordered to remain on supervised probation and make another court appearance after he completes an overseas tour, which kicks off Nov. 14, according to AP. Superior Court Judge Patricia Schnegg did not address questions raised at a previous hearing about whether the R&B singer had completed the terms of his community sentence. Brown's next court date is Jan. 17.

Rihanna told Oprah Winfrey in an emotional August interview that she and Brown now had a "very close friendship."

Other collaborations on Rihanna's upcoming Unapologetic album include Eminem, David Guetta, newcomer singer-songwriter Mikky Ekko and rapper Future.
