The City alum and social media superstar, 29, took a dip in the ocean wearing Heidi Klein's lemon-hued "Cassis" bandeau bikini (on sale for $116 from $233). She tied her hair up into a messy bun, and finished with a pair of tortoiseshell sunglasses.

Meanwhile, her husband since June 2014, 38, worked his ripped body in navy-blue swim trunks. The duo took turns sharing a bright orange tube, pushing each other back and forth and giggling all the while.
