Joan Rivers' apartment sold to Middle East royalty

Joan Rivers' lavish Manhattan triplex apartment has sold to "Middle East royalty" after multiple offers from several parties, sources close to the comedienne's family told CNBC. The deal closed earlier this week for the asking price of $28 million. The apartment, on the Upper East Side, was listed in February of this year. Rivers died unexpectedly while undergoing an endoscopy in September of 2014.

The four-bedroom, 4 ½-bathroom condominium spans the top three floors of the building at 1 E. 62nd St. Its ornate décor, soaring ceilings and gilded balcony prompted Rivers to joke, "It's what Marie Antoinette would have done, if she had money."

The home was sold by Rivers' daughter Melissa, who had her own apartment within the triplex. The buyers, who closed on the deal unusually quickly, likely paid cash.
