CHRISTINE McGuinness broke down in tears after making an emotional admission about her three children on BBC's Pilgrimage: The Road Through North Wales.
The 36 year old was one of seven celebrities who took part in a 137-mile trek to try to understand each other’s different religious and spiritual backgrounds.
In an episode of the BBC Two show Pilgrimage, Christine was reduced to tears as she discussed dying and leaving her children behind with a female vicar.
Taking to her Instagram, where she has 735K followers, the mum of three shared a short clip from the show.
In the heartbreaking clip, the TV personality is sitting outside a church and can be heard saying to the vicar: "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. It just makes me want to be around forever because they're so magical.”
Holding back tears, she bravely admitted: “It is my purpose in life, and I know I wouldn't be here if I didn't have my children. I also don't know what they'd do without me; it scares me, it really does.”.
As the tears rolled down her face, Christine wiped them away from her face in the heart-tugging snippet.
The post was captioned: "The reason you’re alive is to chase dreams that seem crazy to most people but feel like destiny to you.
"My dream is to make our wonderfully diverse world a more inclusive and understanding place for future generations. Blessed to have this shown during World Autism Acceptance Week.

Christine and ex-husband Paddy McGuinness share twins Leo and Penelope, 10, and Felicity, seven.
Since the proud mum experienced the life-changing journey, she has admitted that she's no longer afraid of dying.
Last week, during an episode of The One Show, Christine told hosts: "I took away so much. For me personally, it was not being so scared of dying anymore.
"That was something that was really keeping me awake at night, I've got three children."
Amanda Lovett, Tom Rosenthal, Eshaan Akbar, Michaela Strachan, Spencer Mathews, and Sonali Shah starred alongside Christine on Pilgrimage.
