Supermodel Christie Brinkley is putting her four-bedroom, two-bath oceanfront home in Water Mill, N.Y., on the market for slightly less than $8 million.

Brinkley, who filed for divorce from cheating husband Peter Cook last July, purchased the home and some nearby property on Flying Point Road in December 2005 for $4.9 million.

The home is being listed with Susan Breitenbach, senior vice president of The Corcoran Group, who declined to comment on the sale. Brinkley's representative, Kathy Lynn, said Brinkley was "on vacation" and not available for comment.

Brinkley, 53, and Cook, 47, reportedly own $60 million worth of real estate on Long Island and elsewhere, including a 4.4-acre spread on Fahys Road in North Haven, which was purchased in 2004 for $7.1 million. The unoccupied six-bedroom Greek Revival residence was where Cook romanced his girlfriend, Diana Bianchi. Sources told Newsday last year that Brinkley originally purchased the house as a gift for her architect husband.

Cook is Brinkley's fourth husband. The couple married in 1996 and have two children, an 8-year-old daughter, Sailor, and an 11-year-old son, Jack, Brinkley's child from a previous marriage whom Cook later adopted.

Brinkley also has a 21-year-old daughter, Alexa, from her previous marriage to singer Billy Joel.

Incidentally, Joel has had his 14.6-acre estate on Centre Island on the market since last year, recently lowering the asking price from $37.5 million to $32.5 million.
