Candy Spelling, widow of the late TV producer Aaron Spelling has sold the mansion to a 22-year-old British heiress Petra Ecclestone on Tuesday.

The 57,000-square-foot Spelling's mansion was ranked as America's most expensive home. The French chateau-style house known as The Manor was listed at $150 million two years ago, though the amount being paid for it has yet to be reported, WSJ reported.

The buyer, Petra Ecclestone, is a 22-year-old heiress to her billionaire father Bernie Ecclestone's Formula One racing empire.

The Manor was built by Spelling and his wife, Candy, in 1991 in Los Angeles, which is slightly larger than the White House.

The 5-acre property has more than 100 rooms, a staircase inspired by the sweeping stairway in the film Gone with the Wind, and multiple flower-cutting and gift-wrapping rooms, the Journal said.

Aaron Spelling was one of Hollywood's most prolific TV producers who died in 2006 at age 83. Some of his prime-time series are Beverly Hills, 90210, Melrose Place, Dynasty and The Love Boat.
