An extravagant Beverly Hills mansion is for rent at a whopping $600,000 a month. The lux pad was once homes to the likes of William Randolph Heart and Marion Davies and where John and Jacqueline Kennedy honeymooned.

The mansion is listed by agent Jeffrey Hyland of Hilton and Hyland and the Los Angeles Times reported that the agent says it could be "the most expensive lease in the country."

The extravagant abode includes 17 bedrooms, 29 bathrooms set in more than 50,000 square feet on 3.7 acres of land.

The mansion has an in-house theatre, a billiards room and a stunning two story library that is lined with wooden shelves and a wrap around walkway with railing.

"Designed by Davies and Hearst to double as a theater complete with a drop-down screen and built-in projection portals, the 22-foot-tall living room also has served as party space over the decades. It was the site several years ago of a 60-person sit-down dinner for Prince Albert II of Monaco....

The nearby billiards room is a more intimate space with a coffered wood ceiling, a fireplace surround moved down from Hearst Castle in San Simeon and an 1888 Brunswick pool table," reported the LA Times.

The Chicago Tribune reported that the house was built in the 1920s by a banker, Milton Getz and is a Mediterranean style beauty.

Leanord Ross, who was an attorney and investor was the mansion's fourth owner for more than thirty years and during his time there spent a lot of money renovating, restoring and adding more than 20,000 square feet of living space on the four leveled place.

"It has been a labor of love," Ross said a few years ago reported The Chicago Tribune. "This is not a spec house."

The wing that Ross added to the house includes Art Deco décor, carved glass and mirrors and a bar from Hugh Hefner's club Torch. Upstars there are family bedrooms and staff quarters that lead to large central hallway.

The mansion has been used in movies such as "The Godfather" and "The Bodyguard" reported The Chicago Tribune.
