Amanda made the comments during a heated debate on This Morning with relationship therapist Louise Van Der Velde, who believes women should get cosmetic surgery to stop their husbands and boyfriends cheating (!).
When Louise, 41, asked Amanda, 43, if she had previously undergone Botox or surgery, the actress said: "Everybody knows that in the past, yes, I've talked about having Botox. Since spending too much time in intensive care after nearly losing a baby, I've not gone under the knife or had any injections.
"To be absolutely honest, I now have a team of amazing people and I have non-invasive stuff.
"But I have facials, I buy things from well-known chemists, it's not how I look physically, it's how my husband and how I feel about myself.
"My husband tells me, every day, wonderful things."
Louise, who runs a relationship therapy centre in central London, claimed that women in their forties should get plastic surgery or face their partner running off with a younger model.
She believes women only have themselves to blame if their husband starts to find other women more attractive.
In August, Amanda said she has decided not to try for another child after experiencing a miscarriage and a stillbirth.
"I can't put my family through that again," she said.
Amanda and her husband Chis Hughes have two daughters, Alexa (Lexi), eight, and Hollie, two. Following Hollie's birth, Amanda spent three days in intensive care and says she 'came close to death' after suffering huge loss of blood.
Before Hollie was born, Amanda had a miscarriage in 2010 and a stillborn son in 2011.
"If I could, I would have more kids, but I can't put my family through that again," Amanda told Essentials magazine.
"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. We're incredibly lucky to have our girls."
