Heather Mills has vowed to never marry again.

The former model, the estranged wife of Paul McCartney, also denied being romantically involved with her personal trainer Ben Amigoni.

In an interview with US TV show “Extra, which was aired on 21^st November” Heather said: “I haven’t got a lover. At the moment I am focusing on my daughter.”

“I will never marry again. I’m a good mother, I’m a good person.”

Heather also revealed she struggled to conceive three-year-old Beatrice and classes becoming a mother as he greatest ever accomplishment.

She said: “I tried for a long, long time. I had two entopic pregnancies and six miscarriages. They told me I could never have children.”

Heather slammed claims that she is a “gold-digger” and said she had been completely in love with Paul, 64, when they married.

She said: “I fell in love for the right reasons. I fell in love unconditionally.”

“Eighty-five per cent of my income goes to charity. The word gold-digger doesn’t go with that. If I was a gold-digger, I would have a lot of money in my bank account and I would be worth millions.”

The 38-year-old blonde insists she has had a lot of public support since she split from The Beatles legend in May.

She said: “I didn’t know that many people cared. I have had people hugging me in the street.”

“You get to know who your friends are and I haven’t lost any friends.”
