She said: "I don't think that's something that people shouldn't talk about, because... it was unfortunate but it happens."
Doctors eventually discovered the star has a rare MTHFR gene mutation which caused her body to attack a foetus when she fell pregnant. After two cycles of IVF she gave birth aged 39.
Courtney has also admitted she regrets going under the knife after Botox and fillers left her face looking almost unrecognisable.
She said in an interview: "You have no idea because it's gradual, until you go, 'Oh, s***. This doesn't look right.' And it's worse in pictures than in real life."
