Bobby Brown has lost another child ... his son, Bobby Brown Jr., has died.
A source close to the family tells TMZ Bobby Jr. was found dead Wednesday in his home in the L.A. area. Police are still at the house, and our sources tell us, at this point, they do not believe there was foul play involved.
It's another horrific tragedy for the singer and his family to endure. Bobby Jr.'s half-sister, Bobbi Kristina, died when she was just 22 years old after she was found lifeless in the bathtub of her Georgia home.
She was on life support for several months before she passed in July 2015. The coroner determined Bobbi Kristina's cause of death was drowning in the tub while she had toxic levels of cocaine and alcohol in her system.
