But, after suffering the trauma of a miscarriage in 2010 and a stillbirth in 2011, Amanda has vowed never to try for more children.
Speaking with Essentials magazine, the Britain's Got Talent presenter said she ‘came close to death’ when Hollie was born in 2012 after suffering a huge loss of blood and spending three days in intensive care.
She added: "If I could, I would have more kids, but I can’t put my family through that again.
"Chris and I were talking about this the other day, saying how if we’d met earlier we’d have had more kids, but that you end up with the ones you’re meant to have.
She added: "We’re incredibly lucky to have our girls."
She and record producer husband Chris Hughes were devastated when Amanda gave birth to a stillborn son in 2011, with the mum-of-two opening up about the horrific trauma of the event in an interview last year.
"It was me wailing and making the most horrific guttural noises. Everything came tumbling down."
"From somewhere in the hospital I could hear the most horrendous screams. I thought it was the labour ward until I heard my daughter's name being shouted out animalistically.
"It was me wailing and making the most horrific guttural noises. Everything came tumbling down."
The 43-year-old will now take over from Holly Willoughby on This Morning, as the star heads off for her maternity leave in September.
