Lisa Snowdon has never had kids because she "wasn't in happy relationships".
The 44-year-old radio host - who previously dated George Clooney for five years - insists that while she wanted to become a mother when she was younger, she has never got pregnant because she was conscious about having an "unhappy pregnancy".
She said: "I always wanted to be a mum when I was younger - it was something I always imagined doing and being.
"But slowly over the years it just hasn't happened for various reasons, mostly the fact that I wasn't in happy relationships and I just didn't want to have a baby and not have a happy home.
"I didn't want to have an unhappy pregnancy, I just didn't."
Lisa - who is now dating her longtime pal George Smart - insists she has "come to terms" with the idea that she will never be a mum.
She added to The Sun newspaper: "It's something I have kind of come to terms with. A lot of the younger ones in there want children or have children."
After dating 55-year-old Clooney, Lisa embarked on relationships with footballer Jay Bothroyd, 34, and 'CSI: Crime Scene Investigation' star Gary Dourdan, 49, as well as communications manager Adereti Monney, 38.
Earlier this week, Lisa was voted off 'I'm A Celebrity... Get Me Out Of Here!', and during her time in the Australian jungle admitted she "let it late" to have kids.
She said: "[I don't want] children] now. It's a weird one because it's so hard. I left it kind of late. I didn't find anybody that I wanted to actually be with and I didn't want to have kids to just [to have kids], I wanted that unit kind of thing."
