The meeting in East Hampton, N.Y., last week was the first in more than two months between the British rock star and his soon-to-be ex-wife, activist Heather Mills, The Daily Mail reported Monday.
The feuding couple made the decision to sit down and call a truce out of concern for their 2-year-old daughter, Beatrice. The little girl had started showing some behavioral problems, such as throwing tantrums, the Daily Mail said.
McCartney, 64, and Mills, 38, talked alone for about 40 minutes.
"Both of them have very different views as to why their marriage collapsed," a friend told the tabloid. "But they agree the most important thing is little Beatrice."
