Bobby, who refused to even utter Nick's name while talking to ABC News, has also joined the wrongful death suit filed against Nick in the wake of The National ENQUIRER's
bombshell reporting on Bobbi Kristina's mysterious death. She was first found unresponsive in a bathtub in January 2015, and died in hospice care
six months later at the age of 22. The drug-filled body
of Whitney, 48, was found dead at a Beverly Hills hotel in February 2012 — also in a bathtub.
