Feb. 18: On Yoko Ono's 81st birthday, we look at her real estate

Yoko Ono, the artist and musician who is most famous as the widow of slain Beatle John Lennon, was born in Tokyo on this day 81 years ago -- Feb. 18, 1933 -- so Yahoo Homes is looking at a couple of her properties.

The home pictured above is a converted horse stable that she bought for their son, Sean Lennon, in 1995. He lived in the penthouse on Downing Street in Manhattan for only a few years, after which it sat empty. She said she'd been trying to sell it but the co-op board stood in her way. The listing can still be found on Yahoo Homes, although it appears to be under contract.

As for her own residence, Yoko Ono still lives at Central Park West and 72nd Street on Manhattan's Upper West Side, in the Dakota co-op, New York's most exclusive building. (Rejected applicants for residence have included Madonna, Billy Joel, Cher, Carly Simon, Judd Apatow, Antonio Banderas and Melanie Griffith, Alex Rodriguez and Tea Leoni.) Her husband was gunned down in front of the building in 1980, just a few feet away from her.

Her next-door neighbor Roberta Flack told the New York Times a few years ago that she used to hear the couple rehearsing music. They'd moved away from a loft on Bank Street in New York because they wanted better security, photographer Bob Gruen told the Times.
