Michael and Juanita Jordan

Juanita Jordan could possibly "get more than $150 million in a settlement, making the Jordan divorce the most expensive in entertainment history," Forbes said.

Neil Diamond, whose 1995 divorce from Marcia Murphey cost him an estimated $150 million, holds second place.

Steven Spielberg comes in third for paying his ex-wife Amy Irving an estimated $100 million, which was then half his fortune, when they divorced in 1989. The Oscar-winning director is now worth $3 billion.

Also making the list are estimated settlements between Harrison Ford and Melissa Mathison ($85 million); Kevin Costner and Cindy Silva ($80 million); Paul McCartney and Heather Mills, whose divorce could cost him more than $60 million; James Cameron and Linda Hamilton ($50 million); Michael and Diandra Douglas ($45 million and two homes); Lionel and Diane Richie ($20 million); and Mick Jagger and Jerry Hall ($15 to $25 million).

Forbes said they researched divorces of the last 25 years in compiling the list, which was posted Thursday on its Web site.

The results were also the subject of a one-hour special aired Saturday (6 p.m. EDT) on the E! Entertainment Network.
