Heather Mills suffered a miscarriage while married to Paul McCartney

Heather Mills suffered a miscarriage while married to Paul McCartney, it has emerged.

Music legend Paul -- who is set to pay the former glamor model almost $50m in their divorce settlement -- revealed in his High Court battle that Heather, 40, had a miscarriage in the first year of their marriage.

Paul, who has a four-year-old daughter, Beatrice, with Heather, told the court: "We stopped using contraception the night we were married. There was never any question of us doing so before the wedding.

"Heather had one miscarriage before Beatrice was conceived. Neither of us contemplated children without marriage."

The ex-Beatles' statement was published in Mr. Justice Bennett's explosive 58-page judgment yesterday.

Paul also revealed he was "old fashioned" about the idea of marriage and didn't move in with Heather until they married in 2002 -- even though they got engaged in 2001.

He insists he exchanged vows with Mills -- often referred to as 'Lady Mucca' by the British press due to her porn past -- truly believing he would be with her forever.

"After our marriage, the nature of our relationship, to my mind, changed significantly," he said. I was, and remain, fairly old fashioned about marriage. We decided on a proper wedding for that reason.

"I believed it was for life and that it put everything on a different footing. I drew up a will to include Heather."

The judge also ruled that it was "completely unrealistic" for Heather -- who originally demanded $250 million in her divorce settlement -- to continue to enjoy the same lifestyle she had with Sir Paul.

He said: "After a short marriage to a very wealthy man, it is unfair to expect that she should continue to live at the same 'rate'. Such an expectation is completely unrealistic."
