The R&B star has joined Bobbi Kristina Brown's court-appointed conservator, Bedelia Hargrove, as a plaintiff in the civil case against the tragic 22-year-old's boyfriend Nick Gordon.

Brown's name was added on 4 May (16), days after Hargrove filed a renewed motion for monetary sanctions against Gordon on the grounds of his complete disregard of the court, according to People.com.

The renewed motion came just days after Nick gave his version of the events that occurred on the day Bobbi Kristina was found face down and unresponsive in a bathtub at the couple's Roswell, Georgia home during an appearance on America's Dr. Phil show.

He also attacked Bobby Brown on the show, telling Dr. Phil, "He (Bobby) hurt his own daughter, not me. I was the one there for her while she was dealing with him not being there. He's not a reasonable person so I'm not planning on talking to him and I really don't want to."

Brown famously banned Gordon from seeing Bobbi Kristina as she battled for life in hospital. She passed away in July (15).

Bedelia Hargrove subsequently made it clear she did not approve of Gordon's TV appearance.

"The defendant ignores this Court's mandates but freely discusses his role in the incident which led to the horrific injuries to Decedent Bobbi Kristina Brown on public television," she stated.

During his interview with the TV self-help guru, Gordon said he "ignored" the wrongful death lawsuit "and its consequences".
