The 22-year-old daughter of late singer Whitney Houston and Bobby Brown is seen lying in her casket in the picture, which was snapped during private viewing of her funeral, reported ET Online.
The photo was apparently sold to the National Enquirer and the purchase price went into six figures, according to a source.
The Brown and Houston families have blamed each other for the security breach.
The families had feared that this might happen, as a photo of Whitney Houston's body in her casket was also leaked back in 2012.
Brown died in hospice care on July 26, six months after being found face down and unresponsive in a bathtub at her suburban Atlanta home.
