Brown Jr. was found dead at his Los Angeles-area home Wednesday, according to TMZ. Foul play was not suspected, the outlet reported.
The younger Bobby was the son of Brown, 51, and Kim Ward, with whom Brown had an 11-year off-and-on relationship.
The loss is another tragedy for the New Edition star, who lost 22-year-old daughter Bobbi Kristina Brown in 2015, three years after her mother, Whitney Houston, was found dead in a hotel bathtub.
Bobbi Kristina’s ex-fiancé Nick Gordon, who was found legally responsible for his former partner’s death, also died earlier this year.
Three days after his sister’s death, Brown Jr., also an aspiring musician, spoke out on Twitter about people who flocked to follow him.
“People really don’t give a f–k about you unless you’re relevant,” he wrote in a since-deleted thread, “and they don’t love you till you’re famous or gone. I don’t want these follows. Your follows ain’t gonna fill the hole in my heart, and y’all gon unfollow me once you stop caring.”
Ward gave birth to Brown Jr., the second of her two children with Brown — whom she had known since they were children — less than a year before Brown and Houston had their daughter, Bobbi Kristina. In a 2016 interview with Boston Magazine, Ward claimed that Houston never warmed to the boy and preferred that Bobbi spend time with Brown and Ward’s older child, La’Princia, saying, “[Houston] has a problem with little Bobby.”
