The Madea's Witness Protection star recently wrote a character into the show for the aspiring singer and actress, shortly after the passing of her mother Whitney Houston in February.
Reports claimed earlier this week that 20-year-old Brown had walked off set in the middle of filming, but now show producer Perry has spoken out to dismiss the story.
Perry wrote on his official blog: "NOT TRUE AT ALL PEOPLE!!! There is no way that she could have walked off the set because we have finshed (sic) taping the season… 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.
"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.
"Some days you're smiling and happy and some days you're so broken that you can't stop crying. So, yes she was grieving, but grief aside, she managed to finish her obligation and did a great job at the same time."
Perry also made a plead to the media to stop scrutinizing the budding actress, adding: "PLEASE LEAVE THIS BABY ALONE!!!! AND SHE IS A BABY!!! Please stop the lies and give this child some room to breathe and grieve."
Brown recently made her first public appearance since her mother's death on the Billboard Awards, where she accepted the Millenium Award on her mother's behalf.
She will be seen later this year with other family members on the Lifetime reality show Houston Family Chronicles.
