The 38-year-old model and entrepreneur appeared on the ITV magazine show said that conducting her recent book tour, for her new autobiography "Reborn", in which she recounts incidences of her husband's infidelity, had forced her to re-live those experiences, reported Contactmusic.
"The past two weeks I've been on my book tour and it's opened up some wounds," she said.
"It's been awful. I thought I'd dealt with it. I was numb when it all happened. I'm quite good at putting up a defence. But it's been torture.
