A week to the day he presumably smashed a window at ABC's New York studios in a fit of rage, Chris Brown will make his return to the network,  although  this time on the West Coast, as the volatile R&B star is slated to perform two songs on Dancing with the Stars Tuesday  night.

Brown last week "apologized to anyone he startled" after the incident, following a testy Good Morning America appearance in which he was agitated after ABC's Robin Roberts questioned him about the brutal beating he laid on his then-girlfriend Rihanna in 2009.

The price of Chris Brown’s meltdown on Good Morning America was not cheap -- RadarOnline.com has exclusively learned that the cost to replace the window was $2055.36!

New York business Philip Kaplan Glass Works replaced the broken window after the singer “had to blow off steam and let out the anger” by throwing a chair at the window of his dressing room.

First, he lost his cool, then his shirt -- and now, his publicist.

After a wild week which included an uncomfortable Good Morning America appearance, a broken window and a half-hearted apology, Chris Brown's publicist Tammy Brook has parted ways with the volatile singer, according to the NY Post.

The publicist released this statement to RadarOnline.com about the Brown situation: "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. 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."

Chris Brown "apologized to anyone he startled" after he presumably broke a window ABC's New York City studios following Tuesday's Good Morning America appearance, in which he was agitated after ABC's Robin Roberts questioned him about the brutal beating he laid on his then-girlfriend Rihanna in 2009.

The Forever singer, appearing on BET's 106 & Park on Wednesday, said he "had to blow off steam and let out the anger" after the appearance, in which he wanted to promote his new album F.A.M.E. -- and not dwell on past events.
