After his split from on and off-again ex-girlfriend Rihanna, "Fine China" singer Chris Brown has decided to cut the duet that he did with his old flame from the tracklist of his upcoming album "X."

A source close to Breezy told Hollywood Life that the singer threatened not to drop the album if the song was still on there.

"Just saw the working tracklist for 'X' yesterday -- Rihanna is not on there," the anonymous source said.  "Record execs wanted that song on there, but Chris said he would rather not and wouldn't allow the record to be released unless they took it off."

In RiRi's 2012 "Unapologetic" album Chris was featured in a song called "Nobodies Business."   This was a prelude to their collaboration on "X."  Brown teased fans with the news when he spoke about it with MTV in April.

"So we did 'Nobody's Business' for her album, and then I wrote a song, it's called 'Put It Up.'  It's more of an R&B record," said Breezy.  "I wanted to do an R&B record with Rihanna because I didn't want it to be the same four-on-the-floor, pop.  At the end of the day, that's what they expect from us, so I wanted to do more of a record that nobody really heard her sing on as far as that genre."

Although Chris still has love and respect for her, the unknown source said that communication between them is totally nonexistent.

"They don't talk. They're done.  Nada. Nothing, said the mystery source.  "They're not on that level right now.  He's not thinking about her in any capacity."
