Chris Brown’s occasionally discomforting quest for career rehab hit another roadblock Tuesday, when an appearance on “Good Morning America” concluded with the singer trashing his dressing room and storming shirtless out of the ABC New York studio.

The reported meltdown came off-camera, after an interview with co-host Robin Roberts, who asked him about his 2009 assault of Rihanna, and after he performed a song in the “GMA” studio.

He was scheduled to perform another song after a commercial break, but unidentified witnesses told the Associated Press and other news outlets that Brown went to his dressing room, smashed a window — reports say shards of glass fell several stories onto the street — broke several other items and stormed out as security officers were arriving.

Brown was on “GMA” to plug his new album “F.A.M.E.” (the title stands, he says, for “Forgiving All My Enemies”) which came out Tuesday and already has garnered three hit singles and largely positive reviews. But Brown clearly seemed agitated when Roberts asked him about the assault and continued to emphasize the new album.

“This album is what I want them to talk about and not what happened two years ago,” he said.

Brown is still on probation for the Rihanna assault, but ABC said Tuesday it did not plan to press criminal charges against the singer.

Brown is also slated to appear on ABC’s “Dancing With the Stars” next week; and so far the gig is still on.

KESHA NIXES JAPAN SHOW; CYNDI LAUPER DOESN’T: Pop singer Kesha, known for her gleefully raunchy songs and stage shows, says she has postponed an upcoming concert tour in Japan, in deference to the earthquake, tsunami and ongoing nuclear power plant crisis there.

She urged fans to donate to relief funds.

“My heart is with Japan right now through this disaster and these hardships,” the singer posted on her website. “I genuinely don’t think right now would be appropriate timing for me to perform in Japan given the content and the spirit of my show, which is all about feeling exuberant, rowdy and wild.”

But Cyndi Lauper has decided to go on with her current tour in Japan and will use the shows to raise funds for relief efforts.

ANOTHER DAY ANOTHER LOHAN ARREST: There are new legal problems for Lindsay Lohan’s father, Michael Lohan. He was arrested by Los Angeles police on three felony charges Tuesday after a woman accused him of domestic violence at a nearby apartment, police say.

Police said they arrested Lohan after receiving a call at 9 p.m. about a domestic dispute. Lohan was detained while he was walking on the street near a police station. Police said he did not appear to be intoxicated and was cooperative.

Lohan, 50, was booked for inflicting corporal injury on a cohabitant, false imprisonment and preventing a report of victimization, police said.

No other details of the alleged incident were revealed.

His daughter Lindsay, meanwhile, is expected to inform a judge by today whether she will accept a plea deal with jail time or go to trial in her felony grand theft case.

Reports say a judge has offered Lindsay Lohan a term of 60 to 90 days in county jail, rather than state prison, if she pleads guilty to grand theft, RadarOnline.com reported.

She could face a worse sentence if she rejects the deal and is later convicted.

Lohan is accused of stealing a $2,500 necklace from a jewelry store near her Venice home last month.
