Having finally reached a settlement in his rather long and nasty divorce, you would think the last thing Paul McCartney would want to do is hang out with ex-wife Heather Mills. But according to reports, Paul has invited her to join him on his upcoming world tour.

What in the world would possess him to do such a thing? You can bet it isn't Heather's sweet disposition and smiling face he's looking forward to. Rather, it is the opportunity to spend more time with daughter Bea that has him considering what some feel is a risky proposition.

"He realizes he has to do some kind of deal with Heather, and to keep disruption to a minimum he has come up with this idea," a source told the News of the World. "He feels that letting Heather fly to him where they are touring could be the best way."

Paul's friends are wary. "Many of those close to him are not sure this plan will work. Heather is so unpredictable that anything could happen."

Divorce, like marriage, requires compromise - especially when there are children involved. For the sake of Bea, I really hope these two can work it out. But based on what has gone on in the past, I am not holding out much hope.
