Christine McGuinness broke down in tears as she told how the thought of dying "absolutely petrifies" her.
The 36-year-old model becomes emotional on BBC show 'Pilgrimage' - in which she starred alongside former 'Made in Chelsea' star Spencer Matthews, actor Tom Rosenthal, and wildlife presenter Michaela Strachan, among others, as they embarked on a personal journey on the BBC programme along a route that celebrates Celtic early Christian saints - when discussing death, because her "biggest fear" is leaving her children one day.
Christine - who has children Leo and Penelope, 10, and Felicity, seven, who all have autism, as she does, with her ex-husband Paddy McGuinness - says in a clip of the show: "I just don't know what I'd do without my kids.
"I don't know what I'd do without my babies.
"I just wanted to come back and look at the church again and really appreciate it, because I don't enjoy the feeling of death.
"As a mum it absolutely petrifies me. My biggest fear is leaving my children one day.
"My children are considered different because they're all autistic and so am I, and I have often had comments like, 'I bet you wish there was a cure or something to fix your children,' and I really don't.
"I think every single child is a miracle. But it just makes me want to be around forever because they're so magical.
Christine admitted she "wouldn't be here" if she didn't have her children.
She adds: "It is my purpose in life and I know I wouldn't be here if I didn't have my children.
"I just don't know what I'd do without my kids, and I also don't know what they'd do without me, It scares me. It really does."
