Good genes run in this famous family!
Cindy Crawford gorgeously graces the pages of the September issue of Vogue magazine, where she hits the water in a boat near her Canadian home with her kids, Presley, 16, and Kaia, 13.
In one pic, the 49-year-old supermodel shows off her curves in a plunging green one-piece as her lookalike daughter models a cute striped swimsuit and her son sports white boardshorts.
Another stunning snapshot shows the kiddos taking a dip in the lake near their vacation home in Ontario.
Last summer, Cindy spent a lot of time in Canada writing her book, "Becoming," which features 150 of her modeling images with 50 short essays on topics such as posing nude, the evolution of photography and aging.
"I'm turning 50 next year," she tells the mag. "And at this point, I feel I've learned a few lessons worth sharing."
"But I've gained so much confidence with age," she declares. "That's something I never felt early on, even if my generation of models was paid to radiate it -- the shoulder pads, glamazon, hair out to there, boobs up to here. It would have been nice to have all that confidence in my 20-year-old body."
While Crawford is one of the most famous supermodels in the business, her fame has cost her her privacy. "These days I'm the perfect amount of famous: enough to get a dinner reservation but not enough to get hassled."
