BRIDGEHAMPTON, N.Y. -- Christie Brinkley is selling her New York estate for $30 million.

Newsday reports the 20-acre estate in the Hamptons is called Tower Hill.

Real estate agent Enzo Morabito of Douglas Elliman says the property in Bridgehampton includes an eight-bedroom main house.

He says the house is built around a 100-year-old, 50-foot observation tower and has views of Connecticut, the Atlantic Ocean and "the curvature of the earth."

The paper says Brinkley, a longtime resident of eastern Long Island, has had the property on and off the market since 2002 at asking prices starting at $25 million.

It did not say where the supermodel plans to live if she sells the estate.
