Chris Brown's manager denies having sexual relationship with him

Singer Chris Brown's manager Tina Davis has finally shot down suggestions that she had a sexual relationship with her client, and that it was her racy text message that triggered the row between him and Rihanna.

A report on TMZ.com recently suggested that it was a text message from Tina that initiated the alleged attack on Rihanna by Brown.

However, Tina claims that she only has a strictly professional relationship with Brown, and nothing more than that.

"The relationship between Ms Davis and Mr Brown is that of manager and client. There has never been any other relationship. The rumors in circulation are false," the New York Daily News quoted her lawyer Marshall Grossman as saying.

"There are no e-mails between Ms Davis and Mr Brown of the type which have been described in media reports," the lawyer added.

The identity of the texter still remains unidentified, as neither Rihanna nor Brown are ready to reveal the true facts about the alleged attack and what actually triggered it.

"Rihanna is just not talking to the people on her team. Chris also isn't talking to his management. Everyone is waiting for them to clear up all the questions and reports. But neither of them is communicating," a source said.

Meanwhile, the Umbrella hitmaker made her very first outing to celebrate her belated birthday, after hitting the headlines for allegedly being attacked by Brown and left with horrific injuries.

"She was in great spirits having a ton of fun," a source said.

However, Brown was not in attendance at Rihanna's belated birthday celebration. "No sign of Chris Brown," the source added.
