Christie Brinkley, 72, and her daughter Sailor Brinkley Cook, 28, drew attention for their striking resemblance at John Mayer's SiriusXM live performance in New York on 26 August 2026, with both wearing coordinated denim outfits. The appearance is the latest in a run of moments highlighting how closely mother and daughter resemble each other, feeding a wider social media fascination with Brinkley's youthful looks.

Cook wore a denim-on-denim look of jeans and a jacket over a black tank top, while Brinkley paired denim jeans with a lace-trimmed black tank top and a green jacket. Footage shared by Hello! magazine prompted admiring comments from fans about Brinkley's age, echoing a similar reaction to a recent Instagram post promoting her new zero-sugar prosecco line, in which followers said they mistook her for her daughter. The pair, who share a 44-year age gap, have previously spoken about matching with the same men on dating apps, and Brinkley, married four times, has also shared her views on relationships in past interviews.
