Sofia threw her arms around Scott as they shared a passionate kiss in the ocean water.

It seemed she only had eyes for the notorious womanizer, as she gazed at him with doe-eyed wonder.

After heating up the waters, the duo splashed around the shallows, where the daughter of music legend Lionel Richie displayed her gravity defying derriere and a hearty dose of side-boob.

Although Scott is 15 years older than his love, they smiled and played around like children.

The pair then took to their lounge chairs to sunbathe.

Sofia cuddled with her older man, draping herself over his chest while he sipped on a drink.

After getting enough rays, the model tossed on a striped robe and stepped out of the sun.
