Christie Brinkley, 69, and her daughter Sailor, 25, could pass for SISTERS as they party on the beach

Holiday actress Christie Brinkley certainly has a youthful glow.

And the 69-year-old New Yorker looks so young that she could pass for her young daughter's sister.

This weekend, the model posed with her mini-me child Sailor, 25, at fashion designer Donna Karan's New Year's Eve beach party, which included fireworks.

And they seemed to be about the same age, even though Christie will be 70 years old in a month.

Brinkley stood out in a red dress as she wrapped her arms around Sailor, whose father is Peter Cook.

The former Sports Illustrated Swimming Issue cover girl was every bit the proud mom.

She put on a leggy show in a black top and green miniskirt.

The glamorous trio look more like sisters than mother and daughters.

She paired this with a stylish black low-cut top with a thick sash around the neck, while she added extra height to her statuesque frame with stiletto ankle boots.

The blonde beauty wore her tresses in soft waves, parted at the side, while her beautiful features were accentuated with smoky shadow, feline hints of liner and a hint of berry shimmer.

She added a touch of sparkle with crystal chandelier earrings.

Model Sailor was the spitting image of her famous mother in a scarlet patterned bustier top paired with a contrasting gold leopard print silk skirt with a ruffled hem.

She paired the slinky ensemble with nude sandals.

Her caramel-colored locks were styled sleek and straight, while her beautiful features were accentuated with a radiant layer of makeup.

Singer-songwriter Alexa Ray struck a sultry pose in a racy corset with a sweetheart neckline, which she paired with leather leggings.

Her dark brown locks were pulled into a braided ponytail with an elaborate quiff.

The star went for vampy makeup, including smoky shadow and matte pink gloss.

Christie has been married four times, first to François Allaux and then to Billy Joel, during which time the couple welcomed their daughter Alexa.

The beauty married Richard Taubman between 1994 and 1995 and Peter Cook the following year.

Christie and Peter split in 2008 after welcoming son Jack and Sailor.
