Bikini babe: Megan Williams, 22, showed just why high-profile brands enjoy working with her when she hit the beach in St Barts with boyfriend Richie Akiva on Friday

She tied her locks up in a messy knot and covered her eyes with a pair of black shades.

However, as she made her way deeper into the water with her nightclub owner beau, she let her hair down as they lovingly frolicked in the Caribbean sunshine.

Megan climbed onto a smiling Richie's shoulders and waved her arms around as she struggled to keep her balance.

She fell backwards into the ocean with a splash and Richie pulled her around to his side.
