The math on the Paul McCartney-Heather Mills divorce is as follows:
After 5 years of marriage, he paid her $49 million. Assuming he got sex every night during their 5 year relationship (which would NOT have happened!) it ended up costing him $26,849 per time.
This is Heather. 
On the other hand, Elliot Spitzer's call girl, Kristen, an absolute stunner with a body like no other, charges $4,000 an hour. For anything!
This is Kristen.
Value-added benefits are: a 22 year old hot babe, no begging, no coaxing, never a headache, plays all requests, ability to put BOTH legs around you (!!!), no bitching and complaining or 'to do' lists. Best of all, she leaves when you're done, and comes back when you ask her. All at 1/7th the cost, with no legal fees.
Sometimes renting makes far more sense.

Have no idea why he married her when he was so clearly not over his first wife...he may well have treated her badly if he was constantly comparing her to the first one, whose name evades me...HLOL...so memorable...Linda...I think...And the hooker looks great but sex for money isn't quite the same as sex for love, but, as you say, for Paul, a hell of a lot cheaper in the end...Heather got a raw deal from the press I think, but did okay financially in the end, and you never know what went on behind those closed curtains...she might well have earned every penny...GBHs 
And what of love?
