Continuing to enjoy their vacation in paradise, Olivia Palermo and Johannes Huebl hit the beach in St. Barths on Friday (January 10).

The "City" star took off her button-down shirt and light lacy shorts to reveal a pink and orange bikini and she and her model fiancée floated in the water in inner tubes.

Sharing photos of their romantic getaway on Instagram, the former reality star gave a glimpse of her sexy beau's humorous side.

Earlier in the week, Olivia shared a pic of Johannes with an inflatable peanut M&M on his shoulders with the caption, "Fast friends! Both big on their sweet tooth!"
