The late comedienne’s lavish triplex penthouse on the Upper East Side of Manhattan was said to be haunted by a spirit named Mrs. Spencer, who was J. P. Morgan’s niece and the original resident. Rivers said she’d even brought in a voodoo priestess and finally appeased Mrs. Spencer after hanging a portrait of her and leaving flowers for her in the ballroom. Now that Prince Muhammad bin Fahd has purchased the residence for $28 million and reportedly plans to gut the place, maybe Mrs. Spencer will make a reappearance.

The country music legend discussed the supernatural activity at her plantation house in Hurricane Mills, Tennessee, on an episode of the Travel Channel’s Ghost Adventures.

The actress has said that the Los Angeles home she shares with husband Alexis Denisof has a “very friendly” ghost, SFGate.com reports. “I’d love to get his name. I’m thinking of putting a little chalkboard where I think he lives to see if he will write his name down.”

The legendary star died at her home in L.A.’s Brentwood neighborhood in 1962, and conspiracy theories surround the circumstances of her death. It is said that her ghost haunts the home, according to Variety.
