Crow, 48, is mum to two adopted sons - Wyatt, three, and Levi, five months - but admitted she is still holding out hope she could have her own natural child.
She said to UK newspaper The Guardian: 'I would have loved to have gone through the whole experience [of pregnancy] myself - and it's not impossible that that couldn't happen still - but I didn't feel like I needed to bring another kid into the world just to satisfy my own needs to become a mom when there were already so many kids in the world that needed one.'
