Sailor Brinkley Cook

Cook's father is architect Peter Halsey Cook who once modeled with her mother Christie Brinkley in 1979.

Cook has two maternal half-siblings: Alexa Ray Joel (born 1985) from Brinkley's marriage to Billy Joel, and Jack Paris Brinkley (born 1995) from Brinkley's marriage to Richard Taubman.

Growing up, Cook wanted to become a comedian or a professional athlete.

During elementary school, Cook participated in dance lessons but nerves got the better of her and she never performed in the recitals.

She started modelling at age 15 after accompanying her mother on shoots and being encouraged to try herself.

Cook received her big break courtesy of a Teen Vogue editorial feature.

They eventually reconnected, and were married from 1996 until their 2008 divorce.

Cook was conceived via in-vitro fertilization and her mother was 44 at the time Cook was born.
