The former One Show presenter is currently step-mum to her husband Frank Lampard's two children, Luna 11, and Isla, nine, but has spoken out saying she would love to have children of her own.
Christine, 37, was hosting the chat show for the first time and admitted to rest of the panel that she would love to have a baby.
She told Martine McCutcheon, Gloria Hunniford and Linda Robson that she's accepted that there will be a day when she won't be able to have children.
'I'm 37 but in my head I'm about 23/24. Of course you have to get your head around that biologically you can't have babies forever.'
She added that she loves being a step-mum but has also thought about having children with Frank 'I certainly would love to have children. I think with Frank having two little girls, you've got a strange sense of motherhood without being a mummy, but it is a wonderful thing.'
Christine said that while her parents have never put pressure on her for grandchildren, she admitted: 'I know they'd secretly adore it.'
While the television presenter said she's not spent too long thinking about IVF, if there were problems with fertility in the future Christine admitted it's something she's considered.
'I would probably [have IVF]', she told the panel. 'I have very close friends that have gone down that road and I know it can be incredibly difficult, you go through various round and they don't' work, it can be very stressful for a couple.
'It's one of those things where you just think, "Well, I'll put my trust in whatever it is up there." But if you're told you can't, then that's when I think I'll go down that route.'
However, the presenter has also hit out at the criticism she's received for not having children. In an earlier appearance on Loose Women, she talked about what it's like to be married in your late 30s, without having a child.
She said: 'Oddly enough at 37, if you don't have babies, it's all I get asked.
Firstly it's: "Oh you're 37! No babies yet?" That's a really big question. It doesn't bother me really but it's something I would never ask another girl.'
