Bobbi Kristina Brown's aunt Leolah Brown took to Facebook to write a letter to Dr. Phil McGraw to express her disappointment about Nick Gordon's recent appearance on "The Dr. Phil Show."

"Dr. Phil, with all due respect, Nick Gordon is under investigation for the attempted murder of my niece Bobby Kristina Brown," Leolah started her open letter posted on her Facebook account.

According to Leolah, they have "strong evidence of foul play" so she requested that McGraw "or anyone else not provide this individual a platform to spin this situation to his benefit" until the investigation is completed by law enforcement.

Leolah added that Gordon does not deserve to have a platform to speak to anyone of McGraw's caliber if he does not have the courage to speak with her brother Bobby Brown and law enforcement about what happened the day her niece's body was found in a bathtub.

With his mother Michelle, Gordon will appear in the "The Dr. Phil Show" episode that will air on March 11 on CBS and was taped in Atlanta.

In the episode, Gordon took part in an "emotionally charged" intervention and admitted to having suicidal thoughts if Bobbi Kristina did not survive. His mother, on the other hand, revealed his severe depression and drug abuse.

After his appearance on the "The Dr. Phil Show", Gordon was reportedly "distraught" and had already checked into rehab, a source close to the Browns revealed to People.

Still in a medically induced coma, Bobbi Kristina is showing "absolutely no signs of life lately," a source told Fox 411.
