Age-defying Christie Brinkley, 72, and daughter Sailor, 28, look like TWINS as they don matching ensembles for star-studded Hamptons event

Christie Brinkley continued to show off her unbelievably youthful looks on Wednesday as she and her daughter Sailor Brinkley Cook enjoyed a night out together.

The 72-year-old supermodel and her 28-year-old daughter, who works as a Ford Model, attended John Mayer's live performance for SiriusXM at The Stephen Talkhouse in Amagansett in The Hamptons.

Posing on the red carpet before the performance, it was difficult to see the 44-year age gap between the duo.

The blonde bombshells wore matching blue denim outfits, accessorized with belts and boots, and left their long locks flowing for the occasion.

After beaming on the red carpet, the pair took the fun inside where Brinkley noted in an Instagram Story video posted on Thursday: ‘John Mayer and the full moon were both amazing last night!’

The clip showed the lookalike mother and daughter singing to the live band. 

Brooke Shields, Howard Stern, Andy Cohen, David Burtka and Neil Patrick Harris were also among famous guests in attendance.

Brinkley’s latest appearance comes just weeks after she was mistaken for her daughter after posting sultry images of herself in front of a Ford F-100 truck to promote her prosecco brand.

Brinkley's amazed 1.7 million followers took to the comments section, including one Instagram user who prayed: 'Please dear Lord let me age like @christiebrinkley.'

'I thought you were your daughter for a second!' another fan wrote.

The Uptown Girl author welcomed her lookalike nepo baby during her fourth marriage to architect Peter Cook, which ended in 2008 after 12 years.

Brinkley is also mother to 40-year-old daughter Alexa Ray Joel and 31-year-old son Jack Brinkley-Cook.

Jack is from Brinkley's third marriage to ex-husband real estate developer Richard Taubman, which ended in 1995 after less than a year.

The Michigan-born, Malibu-raised beauty welcomed her eldest Alexa during her nine-year marriage to five-time Grammy winner Billy Joel, which ended in 1994.

Brinkley opened up about aging in a recent interview.

'I think that with age you get... freer,' Brinkley told her Social Life Magazine cover story in June.

'You do what you wanna do when you wanna do it. I think that there's a freedom that comes with age that's quite wonderful. You don't really care what anybody thinks about your outfit anymore.

'You know what you like. You know what you don't like. And you don't feel like you have to put up with the stuff that you don't like anymore.'

And while the life-long vegetarian has admitted to using 'Botox in my forehead two times' and laser treatments, she reportedly only gets injectable filler once a year on her marionette lines.

The Hamptons resident will next portray the older Kelly opposite Steve Guttenberg's older Mikey in director Michael W Gray's coming-of-age family comedy American Summer, which hits limited US theaters September 4.

Brinkley also keeps busy running her clothing company, Tower Hill.
