Nick Gordon ''hates'' Bobby Brown.

The star has admitted he is missing his girlfriend Bobbi Kristina Brown - who is currently in hospital fighting for her life after being found unresponsive in a bath on January 31 - and her late mother, who died in 2012.

He also insisted he is angry at Bobbi Kristina's father, claiming that he was not allowed to visit her whilst she is in hospital.

In an excerpt from the 'Dr. Phil Show', he said: ''I miss Krissy and Whitney so bad. I want them back...I hate Bobby Brown.''

The show's host Dr. Phil McGraw made the trip to Atlanta to stage an intervention between Nick and his mother Michelle.

Nick is reportedly now in rehab but was left agitated when Dr. Phil suggested he should be getting help.

Phil told Michelle: ''Your son, left to his own devices, will be dead inside a week.''

And as Nick became more agitated, he said: ''You've been drinking a lot though, right? I want you to go straight to rehab.''

Nick replied: ''I'm getting frustrated...I'm done with the interview. I'm done.''

The comments were made during an early preview of this Wednesday's (11.03.15) episode of the 'Dr. Phil Show'.

Bobbi Kristina's father insists Nick has previously ''declined'' multiple opportunities to be at her bedside and is ''not as desperate to visit Bobbi Kristina as he wants the world to believe.''

Meanwhile, Leolah Brown has blasted the TV show by claiming Nick is under investigation for ''attempted murder'' and insisting the programme could interfere with investigations made by police.

Writing on Facebook, she said: ''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.''
