Caprice has opened up about her struggle to get pregnant, revealing that she and partner Ty Comfort have "been to hell and back".
The model is expecting a baby boy in September, one month after the couple are due to welcome their first son via surrogate.
Caprice, 41, told The Sun that before her current pregnancy, she suffered a miscarriage, unsuccessful IVF and her surrogate losing a twin baby girl.
"We have been to hell and back. I would have given up all the fame, money and magazine covers in half a heartbeat to become a mum," she said.
Caprice originally fell pregnant in 2011 but miscarried at six weeks. She recalled: "I went to Chelsea and Westminster Hospital in London and they said there were two embryos but no heartbeats - I was miscarrying.
"The pain was unbearable for two days and they kept me in as I kept fainting. It was just terrible."
The couple flew to Los Angeles to begin IVF last spring, but each of the three rounds they tried were unsuccessful. Caprice was then diagnosed with a medical problem that meant the lining of her womb was too thin for the embryos to implant.
"Ty and I were at absolute rock bottom. I completely lost hope. But then there was a ray of light - as we had a number of healthy frozen embryos left my consultant suggested a gestational carrier," she continued.
"On December 10 we found out she was pregnant with twins. I was screaming with joy. We had gone through so much and now we were going to have a boy and a girl."
Caprice then discovered she had also conceived while on ITV diving show Splash!, but "didn't realise until March".
Her surrogate called the next day to explain that she had been ill with flu and had lost one of the twins - their baby girl. Caprice also feared she was having another miscarriage.
She added: "I was emotionally numb. I stayed at home and curled up into a little ball. I thought I was losing my baby and we had lost our little girl. It was enough to push anyone to the brink."
Doctors later confirmed that her baby still had a strong heartbeat. Caprice will fly to California with Comfort at the end of August to welcome her first son via surrogate, before giving birth herself four weeks later.
