Christie Brinkley Separates From Fourth Husband

LOS ANGELES -- Former supermodel Christie Brinkley is separating from her husband, architect Peter Cook after nearly 10 years of marriage.

Brinkley and Cook's separation was first reported by the syndicated entertainment show "The Insider." Brinkley's publicist, Elliot Mintz, confirmed the separation in a statement Tuesday.

"Her immediate concern is for her children, and she's hoping during this obviously difficult time that people will be kind enough to respect her privacy," Mintz said.

Brinkley, 52, has been married three other times, most notably to rock legend Billy Joel, from 1985 to 1994.

She was also married to Jean Francois Allaux from 1973 to 1981 and Richard Taubman from 1994 to 1995.

Brinkley married Cook in September 1996. They have an 8-year-old daughter, Sailor Lee. She had a son, Jack, with Taubman and another daughter, Alexa, with Joel.

In addition to her modeling gigs, Brinkley has appeared in movies like "National Lampoon's Vacation" and fitness informercials.

She also painted the cover to Joel's 1994 album "River of Dreams," and is the subject of Joel's hit "Uptown Girl."
