The 75-year-old actress and her 70-year-old longtime partner, who have been together for 37 years, appeared to be taking in the scenic waters on a boat during their time on the French Riviera.
This is not the first time fans have seen these two out on the water together. The Hollywood power couple costarred in the 1987 romantic comedy Overboard, which centered on a rich socialite (Hawn) who gets amnesia after falling off of her yacht and is convinced by her rough-around-the-edges carpenter (Russell) that she is his wife.
The A-list grandmother rocked a one-piece black bathing suit and beige visor. Her Escape From New York star partner let it all hang out in white and brown swim trunks.
As OK! exclusively reported back in April, the grandparents of seven credit their adorable brood for keeping their love alive and say that it has helped "put some life" back into their relationship. A source explained, "Goldie does yoga with the crew, bakes healthy treats and is great at organizing everything, while Kurt shoots hoops in the yard, plays video games and is an incredible storyteller."
Between Kate Hudson's children (Rani Rose, 2, Bingham, 9, and Ryder, 17) and Oliver Hudson's children (Wilder, 13, Bodhi, 11, and Rio, 7) as well as Wyatt Russell's (their son together) new baby boy Buddy, who was born in March, the two love to entertain their ever-expanding family.
The source explained, "The kiddos never leave disappointed or hungry. In fact, they're often more worn out than their grandparents!"
