Chris Brown and his publicist have gone their separate ways ... TMZ has learned.
The publicist, Tammy Brook, tells TMZ the separation was mutual -- no one was fired and no one quit.
Brook tells us, "I am an entertainment/music publicist and was hired as a publicist, as they often are, to work specifically on his music publicity for the term up to the release of Chris Brown's F.A.M.E. album, which was released on Tuesday March 22 and is entering the Billboard and iTunes charts at number 1 this week."
She adds, "I love and support Chris and it has been an honor to be a part of this album and I look forward to the possibility of working with him again in the future."
