CHRISTIE BRINKLEY's 19-year-old daughter Sailor Brinkley Cook will be featured in the 2018 "Sports Illustrated" Swimsuit edition . . . making her the first SECOND-GENERATION model in the magazine's history.
Technically, Sailor WAS in a photo spread in the last one, but she posed with her mom and her sister, Alexa Ray Joel.
This time she's all by herself, as one of the "rookie" models.
Christie has done the Swimsuit issue nine times since 1975. She's 63.
