Tom Welch, attorney for O.W. Ranch, would not confirm the celebrity's involvement in the venture, saying Winfrey likes to keep her personal life private.

Gideon Kaufman, an Aspen, Colo.-based legal representative for Winfrey and an officer of O.W. Ranch, said: "I'll let the initials stand for themselves."

O.W. Ranch lists an address in care of Bob Greene (search), Winfrey's friend and personal trainer, according to Maui property tax records.

Winfrey and Greene bought 102 acres on Maui's Hana Coast in 2002 with plans to build separate homes. A year later, O.W. Ranch bought the land in Kula.
