Paul McCartney confessed that he cried every day for the first six months he went out with Heather Mills because he was still grieving for his wife Linda.
McCartney, who plans to marry Mills next year, said he was unsure if he would ever be able to love again after Linda died of breast cancer in 1998.
The former Beatle, 59, said of his affair with Mills, 33: "For the first six months of our relationship, I was pretty much crying every day."
"She was very supportive. She was like 'I understand what you're going through'," McCartney said. "That pretty much cemented our relationship."
