The former Sports Illustrated model, and mother of three is preparing for life as an 'empty nester' as her children Jack, 21, and Sailor Brinkley-Cook, 17, spend more time in Manhattan. Meanwhile her 30-year-old daughter Alexa Ray Joel, whose father is musician Billy Joel, has lived in the city for years.

Editors at The New York Post report Christie is selling her 20-plus-acre Tower Hill estate in Bridgehampton, putting it on the market for $29.5 million (£19.8 million).

The estate was built in 1891 and has views from the Atlantic Ocean to the Connecticut shore. It encompasses a 50-foot observation tower, a four-bedroom guest house with greenhouse conservatory, a separate barn/artist studio and a four-car heated garage.

Christie, 62, has been heavily invested in the area for several years. In 2013 she sold a home in Sag Harbor for a reported $10 million (£6.7 million) following her acrimonious divorce from Peter Cook.

It's also reported that four-times wed Christie will now move into one of her smaller properties in the East Hampton and Southampton's Sag Harbor.

The ex-cover girl has been dating musician John Mellencamp, 64, since 2015.
