The source shot down reports that quoted another anonymous source saying the pair had completed recording a song together about their relationship -- only a month since Brown allegedly pummeled Rihanna.
That source, said to be close to producer Polow da Don, had described Rihanna and Brown as "very playful" while recording a song, supposedly about "facing challenges and overcoming the ups and downs of a relationship in which you become stronger."
Not so, the label source told People.
Instead, the song in question, "Bad Girl," was actually a demo recording from last year. Brown and Rihanna had provided vocals to help pitch the song to its eventual takers -- the Pussycat Dolls -- for the Confessions of a Shopaholic soundtrack, the source said.
"Around August or September of 2008, Chris and Rihanna's vocals were recorded as the reference vocals for this demo only," the source told People. "The song was never conceived or intended to be a duet between them, and was later recorded by other artists."
In February, Brown allegedly beat up his girlfriend after Brown reportedly received a sexually suggestive text message from his manager. The manager, Tina Davis, has denied sending the text.
Prosecutors then charged Brown with two felonies.
Doublemint gum and the Got Milk? campaign have dropped Brown, who also withdrew his nomination for two Nickelodeon Kid's Choice Awards.
Meanwhile, Revlon has secretly hired a polling company to see if Rihanna was dragging down its competitor Covergirl's brand, TMZ reported.
