The 66-year-old former model was shocked to hear David - who she was married to from 1970 to 1980 - had died of cancer earlier this month because she expected him to outlive her, and while she wasn't on speaking terms with the 'Starman' hitmaker before his passing she has no regrets about it.

Speaking about being informed David had died aged 69 while she was competing on UK reality TV show 'Celebrity Big Brother', she said: "It was fine except I couldn't believe it. I thought I would die first.

"I don't think anyone knew [he'd been unwell]. In fact let me take this opportunity to say I think ... he staged his passing rather well.

"Our rancour with each other almost kept us going and I realised I wasn't angry anymore and I thought, 'Oh my God.'

"[I have] no regrets whatsoever. He was obnoxious when he was obnoxious and that's it. But I realised the possibility that I would never hear from him again."

Angie and David had son Zowie Bowie, 44 - who is now known as Duncan Jones - together but she hasn't spoken to him for 30 years and admitted she "doubts" he will get in contact with her again.

She explained: "I had Zowie for David ... I said to him, 'I will never fight you for custody.' David and his father were this close.

"What kind of a person would I be if I used my son as a weapon in my tool belt when we got divorced? Is that not disgusting behaviour?"

When asked if that was an act of generosity rather than selfishness, she replied: "Yes it was."

Angie admits it "hurts" being estranged from her son but she would rather try to "close the door" and move on with her life than dwell on their divided relationship.

Speaking on chat show 'Loose Women', she said: "Last time I saw him he was 13 or 14. It wasn't a tricky age, he was busy working, studying, doing what children do, what I did at 13 and 14.

"Yeah I'm sorry I don't really have much else to say about it. That's how I feel about it and it hurts me and when something hurts me I put it in something in the back of my head and I close the door.

"You can ask me till you're blue in the face and I will say, 'Yeah whatever.' "

When asked if David's death will change anything between Angie and her son, she replied: "No, I don't think so."

Earlier this week, Angie quit 'Celebrity Big Brother' prematurely after falling ill, just over a week after hearing about David's passing, and she insists she became unwell because she eventually processed the news that he had passed away.

Speaking about collapsing on her bed on the show, she said: "I got sick because of it [his death]."
