From kissing on beach paths to making out in the water, Gomez, 18, and Bieber, 17, are taking advantage of being away from the prying eyes of L.A. paparazzi, according to Just Jared.
They've also been seen enjoying the activities the island paradise has to offer, including parasailing and riding jet skis with their families.
Bieber also debuted some brand-new ink on this trip. He recently got a tattoo on the left side of his torso reading 'Jesus' in Hebrew. This is the second tat for the singer, who has an outline of a seagull on his lower torso -- a design several members of his family also have.
Both Gomez and Bieber hit up the Billboard Music Awards last Sunday night before jetting off vacation. The pair caused quite a stir when they publicly kissed on camera when Bieber won the award for Best New Artist.
