You know what they say about the couple that plays together!
Biel, 30, sported a skintight, white wetsuit top and showed off her toned derriere in tiny black bathing suit bottoms as she hit the ball back and forth with her shirtless fiancee, 31, who rocked boardshorts.
How does the "Total Recall" actress keep her body beach-ready?
"For me, getting enough sleep, drinking lots of water, having a healthy diet and staying away from alcohol are musts," she told ELLE last June. "It's so boring, I know, but doing those things really helps."
When it comes to her workouts, she's also a big believer in mixing up her routine by alternating between boxing, martial arts and yoga. "Yoga is a constant for me because it keeps my muscles long and flexible," she explained to the mag. And when the weather heats up? Biel says she makes time to hang out in the sun, "playing volleyball and jogging with my dog, Tina."
Timberlake and Biel have dated off and on for the last five years; the pop star proposed to Biel over the holidays with a $130,000 diamond sparkler.
Sources tell Us Weekly the stars are in the midst of planning their summer nuptials.
"It will be a big wedding," one insider shared. "They have lots of people they want to invite!"
