The pair, who have been getting cozy lately, slipped into their swimming gear to play in a waterfall while filming scenes for the next installment, Breaking Dawn, in Brazil recently.
Stewart, 20, shows lots of skin in a revealing white bikini while Pattinson, 24, sports red swim trunks as the two shared a smile while filming last week.
The couple has been heating up off screen recently as well. On Oct. 4, they enjoyed a candlelit dinner at Ago in Beverly Hills, followed by a Jenny and Johnny concert at L.A's Troubadour the next night. – Sara Hammel
