New York, Mar 12 : Singer Chris brown is reportedly keen to appoint a whole new staff.

He is even said to be planning to replace his manger Tina Davis, who allegedly sent him a racy txt message that triggered the row with Rihanna.

On the other hand, though it has been alleged that Brown had a sexual relationship with Tina, she has clearly denied the claims.

According to reports, Brown is upset with his whole staff, including publicity-loving lawyer Mark Geragos and P. R. man Mike Sitrick, as he thinks his apology released by his staff did not sound genuine.

"Chris wanted to apologize [for the alleged beat-down] much earlier . . . and he was upset when the apology was finally released because it sounded so insincere," the New York Daily News quoted a source as saying.

However, Brown''s business attorney, Kenny Meiselas, has denied that he has any intention of changing his team.

"We are very happy with Chris'' team and there are no changes," Meiselas said. (ANI)
