Paul McCartney discussed divorce plans after meeting up with estranged wife Heather Mills this week.

The pair put on a united front by attending a concert at their daughter Bea's pre-school nursery - their first public meeting since splitting five weeks ago.

"It was a little awkward but Paul used the opportunity to stress that Bea's well-being must remain their top priority, despite the looming divorce battle," a source told the Sunday Mirror.

"Paul knows it's likely to get very nasty in the next few weeks with both lawyers fighting their clients' corners as hard as possible. He tried to explain to her that she shouldn't take it personally, it will just be the legal process taking its course.

"Heather was taken aback by Paul's kindness, although some cynics among her friends believe that he could be just schmoozing her to ensure the divorce goes through more smoothly."
