Christie Brinkley's model daughter Sailor, 28, is her twin as she stuns in plunging black gown at NY fundraiser

Christie Brinkley's daughter Sailor Brinkley Cook looked every inch like her glamorous mother's twin as she attended a fundraiser in New York on Thursday. 

The 28-year-old model wowed in a low-cut black dress that clung to her figure as she arrived at Project Healthy Minds' Fourth Annual World Mental Health Day Gala at Spring Studios.

She channelled her iconic mother's, 72, signature blonde bombshell style, letting her tresses cascade down in bouncy waves. 

The nepo baby complemented her look with a sleek black clutch and drew attention to her magnetic eyes with dramatic black liner. 

The nonprofit annual gala champions expanding access to mental health services across the United States.

The event was hosted by Carson Daly, with stars including NBA champion Karl-Anthony Towns and actor Terry Crews also in attendance. 

Earlier this year, Sailor revealed what it was like being raised by a supermodel mom. 

'Growing up with Christie Brinkley as a mom, it's like the [Fountains of Wayne] song "Stacy's Mom,"' she told the California Post in May, before singing her own rendition with the lyrics, 'Sailor's mom has got it going on.'

Despite the pressure that comes with having a famous parent, Sailor admitted that she finds her supermodel mom deeply inspirational. 

'I'm like, "Rock on!" I hope to be a MILF one day, too.'

Sailor, who often shares social media videos with her lookalike mom, added: 'We have a really fun dynamic. She's a Disney princess and I'm the little troll under the bridge being like, "Do something funny!"'

In August, the dynamic duo 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 two.

In February, Christie teamed up with Sailor to model for a campaign celebrating the 100th anniversary of London Jewelers.

'Her biggest advice when it comes to being on a set would be just to be as gracious as you can,' Sailor told People in 2023.

'I always try and introduce myself to everyone in the room. And I always try and acknowledge everyone in the room, because I mean, my job is almost pretty much the easiest.'

'That's what she taught me, is to really acknowledge my surroundings while I'm in it and not be a diva and have fun with the creatives that I'm working with.'

The Uptown Girl author welcomed her lookalike daughter 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. He was later adopted by Cook.

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.
