The anti-landmine and animal rights campaigner, who lost the lower part of her leg after a motorcycle accident in 1993, is convinced she was destined to meet McCartney, with whom she has two-year-old daughter BEATRICE.
She says, "It was like, I love this man but I want out of this life completely.
"But then doors started opening. (Russian) President Vladimir Putin wanted to have a meeting about landmines. President Putin!
And I knew suddenly that was the reason Paul and I had met.
"Obviously we were in love and there was our daughter and everything, but I knew that was the reason.
"Paul can open these doors, but he won't have time to do the work. He needs me because I do the work."
