Channeling a flashback to her very youthful “The Blue Lagoon” days, original beach goddess, Princeton University educated model and actress Brooke Shields swings into the tropics, grasping a knotted rope and gleefully screaming as she bounces into the sea, captioning “Best day ever!!!,” while her friends cheer her on in the background.

Best day ever!!!

Shields was 14 when she starred in “The Blue Lagoon,” alongside actor Christopher Atkins. Directed by Randal Kleiser, the Academy Award nominated classic movie was filmed on Turtle Island in Fiji and followed the story of the two teens falling in love while shipwrecked together on the island.

Around this time, Shields catapulted to fame, starring shortly after in then-controversial but now-iconic Calvin Klein Jeans commercials.

Who can forget Shields coyly stating, “You want to know what comes between me and my Calvins? Nothing.”
