The episode, which will air on CBS on March 11, features an interview with Gordon, 19, and his mother, Michelle, and, as the clip shows, will revolve around Dr Phil trying to convince Gordon to enter rehab, reported People magazine.
"I miss Krissy and Whitney (Houston) so much," Gordon says as he sobs into his hands. He also tells Dr Phil that he "hates Bobby Brown," whom he has been having a very public feud with since Bobbi Kristina was hospitalised on January 31.
Bobbi Kristina's aunt, Leolah Brown, has written an open letter to Dr Phil, asking him to not give Gordon a public platform as there is "strong evidence of foul play" in her near drowning.
"Nick Gordon is under investigation for the attempted murder of my niece Bobbi Kristina Brown. We have strong evidence of foul play. Until this investigation is completed by law enforcement, I would ask that you or anyone else not provide this individual a platform to spin this situation to his benefit.
