Pia Zadora/Marraige had a 31 year age difference and plenty of money!

Zadora married businessman Meshulam Riklis in 1977, when she was 23 and he 54.
Zadora and Riklis bought the Beverly Hills mansion Pickfair Manor in January 1988 from Los Angeles Lakers owner Jerry Buss for almost $7 million. They demolished most of the structure while keeping the guest houses, claiming that termites and time had made repairs difficult. The mansion, which drew its name of "Pickfair" from having once been the shared home of Douglas Fairbanks and Mary Pickford, was torn down and a new 25,000-square-foot mansion was built on the property. Zadora later claimed that Pickfair was razed due to a troubling apparition which appeared to her and children when her husband was away on business. Riklis commissioned a nude oil portrait of Zadora, which greeted visitors.
Zadora and Riklis divorced in 1993, and Zadora remained in the mansion until late 2005 or early 2006, when she sold it to Korean businessman Corry Hong for $17,650,000.

Pia came to national attention in 1981, when following her starring role in the highly criticized] Butterfly, she won a Golden Globe Award as New Star of the Year, and simultaneously winning the Golden Raspberry Award for Worst Actress and the "Worst New Star" for the same performance.
