The film director opened up about how he was supposed to go over to Amy's place the night before she died on Saturday, July 23.
'We were talking on Friday and I was going to go over, because I was finishing up late at work, but I couldn't get hold of her, so I thought she must have fallen asleep,' he told The Sun.
'I sat in and read a book, still no call back. Met some friends and had a drink, still no call or anything. So I went home, sent her a text, saying I was staying up watching a DVD and told her to call as soon as she woke up. If I'd gone over there, I'd have woken her up. We'd have sat up all night watching films.'
The next day he decided to go about his business as usual and prepare for a wedding they were due to attend the next day when he heard the heart-breaking news.
He said, 'I'd gone out to get all my stuff ready for the wedding. It was on a Saturday. I was calling her but couldn't get hold of her.
'I was going to go over with a takeaway on the Saturday night and sit in. We were going to the wedding on the Sunday.
'I had appointments on Saturday morning - normal things. A haircut, pick up shoes and my suit for the wedding. I was thinking it was a bit strange she hadn't called. I thought I'd get all my stuff done and then head over.
'As I left the hairdresser, I saw I had a missed call from Amy's security guy. She was always misplacing her phone, so I thought she had probably just borrowed his.
'I thought, 'I won't call now, I'll go to my office and pick up some shoes I'd left there and call when I get back'. When I got to the office I rang and spoke to the security guy.
'He just said, 'Reg. Something terrible has happened'. You could tell in his voice. He said, 'You better get here straight away'. And that was it. I dropped everything and went.'
He dismissed speculation that the former drug-addict had returned to her old ways. 'Of all the people I have known, Amy was the most genuine. She lived a very normal life. She was really good to live with. She liked watching TV a lot. She liked to make me something to eat when I got in from work. She liked making food and cooking. That was important to her.
'If I got home late she would wait up. She was maybe a bit old-fashioned.
'She was very feminine. She was domestic, she enjoyed being like that.'
