Report: Tina Davis Sent Chris Brown "Booty Call" Text

Celebrity news sources say that Tina Davis, Chris Brown's manager, has been ID'd as the woman behind the text message long believed to have triggered the fight that left Brown charged with a pair of felony offenses and Rihanna beaten senseless.

Davis allegedly sent a three-page text message to Brown's cell phone that sent Rihanna flying off the handle and caused Brown to respond with brutal force.

Davis, who turns 40 this month, was rumored to have had a relationship with Chris Brown when he was only 16. Brown and Davis have denied this took place.

However, the detective's affidavit in the assault case refers to the text message as being "from a woman who Brown had a previous sexual relationship with."

Was Chris Brown cheating on Rihanna with manager Tina Davis?

Law enforcement sources say the text message to Brown talked about hooking up later - and it royally pissed off Rihanna, who slapped and hit him in a jealous rage.

He retaliated, to put it mildly.

Tina Davis could not be reached for comment.

No one can say for sure whether Chris Brown - who is seeking a plea deal with no jail time - is fully on the same page with Rihanna after everything that happened, but the lovebirds are reportedly working on the same track.

Literally! The seemingly reconciled duo is working on a duet that Brown is hoping to include on his new album, which is due out later this year, a studio source dished to E! Online. "They've been working on it together," the insider says.

Wonder if his manager/possible past lover set the duet thing up. Our guess is probably not. In any case, click to enlarge more photos of Tina Davis ...
