Bobbi Kristina's aunt: Ignore Nick Gordon

Leolah Brown, who has been outspoken about Nick Gordon not being a good influence for her niece, Bobbi Kirstina Brown, has now penned an open letter to Dr. Phil.

On her Facebook page, Brown is asking the TV doc not to give Gordon a platform.

She uses the strongest words we've seen and heard since Bobbi Kristina Brown was found unconscious in her bathtub on Jan. 31 in her Roswell, Ga., townhouse.

Leolah writes that Gordon is "under investigation" for "attempted murder."

She asks Dr. Phil not to give him a "platform to spin this situation to his benefit" until he has talked to law enforcement officials.

Roswell police have said from the start it has opened a criminal investigation into what happened.

Dr. Phil is airing an "intervention" with Gordon on Wednesday's episode of his CBS show. Reports have surfaced that Gordon has checked into rehab as a result. His lawyer has not responded to requests for confirmation.

Gordon has been using Twitter has his platform to speak to fans and to share his pain over Bobbi Kristina's hospitalization. He has been asking to get into Emory University Hospital to see her because Bobbi Kristina's dad, Bobby Brown, has not been allowing him near her.
