After much speculation, a full version of Rihanna's controversial new single with abusive ex Chris Brown has finally leaked.

A snippet of the song, initially dubbed "Nobodies Business," and since updated to the grammatically correct "Nobody's Business," hit the 'net last week, but the full version exceeds expectations.

The '90's influenced, piano-powered club track references Michael Jackson s "The Way You make Me Feel," and features a back-and-forth between the reunited duo.

"I sing it to the world, baby give me something/ I'm a be your girl I wanna make you mine/ And it ain't nobody's business," they sing on the hook.

Unapologetic hits shelves Nov. 19.
