The Romijn-O'Connell family rang in 2016 looking happy, healthy -- and incredibly fit.
Rebecca Romijn, 43, and Jerry O'Connell, 41, have been sharing photos from their tropical family vacation with twins Dolly and Charlie via their Instagram pages in recent days, and let's just say that it's hard not to be envious.
They genetically gifted pair revealed their beach bodies -- her in colorful bikinis, him in small Speedos -- as they swam, jumped, dove, frolicked and snuggled during a getaway to celebrate the New Year as well as their daughters' seventh birthday on Dec. 28.
Rebecca also shared a photo of her husband of eight years walking the plank.
Jerry also posted a sweet photo of himself embracing one of his little girls.
Rebecca and Jerry haven't revealed their exact whereabouts, but they're clearly blending right in: The star of "The Librarians" called them "creatures of the blue lagoon" in yet another post.
