Heather Mills wants more than $48.7 million

Even though Heather Mills got paid $48.7 million for four years of marriage to Paul McCartney, she's still not satisfied.

The U.K.'s Daily Mail says the bitter divorcee is hiring "a team of forensic accountants" to examine Sir Paul's finances and prove he's worth a lot more -- up to $1.6 billion, according to her estimate.

And remember the $70,000 per year she got to take care of their daughter, Beatrice? Yeah, not enough.

"Heather says she can prove the amount of money that is being given to look after Bea will not last over the year. She is putting it to the test," a source says. "Even with Bea travelling in economy Heather says it's not enough. She is keeping every receipt -- including her invoice to her security team -- to show that £35,000 is just not sufficient."

Gee, how much do kid's meals at Burger King cost these days?
