Amy Winehouse's father Mitch has addressed the late singer's relationship with ex-lover Catriona Gourlay.
Mitch, 70, and ex-wife Janist, 64, reflected on their late daughter's life as well as her stint in rehab with BBC News on Friday, ahead of the release of documentary Reclaiming Amy next week.
Catriona recently claimed the star struggled with her sexuality, and he said: 'Catriona and Amy, they were sisters. They were more than best friends.

'And if they had that kind of relationship good luck to them. I have no objections – I just wanted Amy to be happy and I know she was always happy with Cat in whatever way. So that’s great.'
Going on to talk about Amy's rehab stints for substance abuse, Mitch said of the time: 'No-one knew what to do. Because obviously the responsibility of the addiction lies with the person who’s struggling with the addiction. As a family we could stand on our heads.
'How many times we had family interventions, I lost count. How many times I took her into rehabs, and she’d walk out the next day.
'It’s very difficult. I don’t think mistakes are the [right word] because there is no right or wrong way to deal with it.'

Catriona said the pair had an 'undefined' relationship where they 'loved each other' but it left the star feeling 'confused'.
She made the confession on the BBC Two documentary Reclaiming Amy, which will air next week to mark 10 years since the singer's death.
'When I was 19/20, I'd already been in a long-term relationship with a girl at this point, so I knew who I was,' Catriona said, according to Metro.
'She [Amy] used to write notes while I was sleeping, "You were the most beautiful girl I've ever seen," and "How can you look as beautiful asleep as you do awake?''
'Our relationship was so unique, undefined, we just loved each other very much and what I took from it, knowing her, is that she was confused about what it made her.'

She continued: 'When you have something that is so undefined for years, it's hard because it's the thing that I think is so fundamental in understanding her and the things that did trouble her.'
Catriona also recalled that Amy once joked in an interview 'I am not a lesbian until I've had four sambucas'.
She added: 'Perhaps people don't realise that there were other
