In a passionate message posted to his Web site titled “Leave This Baby Alone And Stop The Lies Please,” the filmmaker said the report that Brown walked off the set is “not true at all.”

Perry cast Brown on the TBS sitcom, he wrote, after the 19-year-old expressed her desire to act during a conversation at Houston’s funeral.

Brown’s mother died in February of drowning, heart disease and cocaine use.

In an interview with Oprah Winfrey, conducted less than a month after Houston’s death, Brown said of her mother, “I can hear her voice and her spirit talking to me telling me keep moving, baby. I can always feel her with me.” She recently accepted Houston’s Billboard Millennium Award.

Perry said he could relate to Brown because of the death of his own mother, Willie Maxine, in 2009 at age 64. Of Radar’s claim that Brown had to leave the show because of extreme grief, Perry wrote:

Were there tough days for her? Yes of course. Not because of the [acting] or any job-related issues but because of the fact that she had just lost her mother. And being someone who knows about losing their mother, I know grief comes in different ways and you never know when it’s going to hit you or how it’s going to hit you, for that matter. . . .

So yes she was grieving, but grief aside, she managed to finish her obligation and did a great job at the same time.
