Olivia Wilde is enjoying her romantic vacation with Harry Styles in style.

In photos exclusively obtained by Page Six, the "Booksmart" director, 37, showed tons of PDA with the pop star, 27, aboard a yacht in Monte Argentario, a region of Tuscany, Italy, while wearing a navy blue swimsuit.

The bikini featured a sporty balconette top, which she pulled down while tanning her upper chest, and pocket details on the back of the high-waisted bottoms.

It seems Wilde was in sync with her beau, who wore a blue pullover with a baseball hat of the same color along with black Nike running shorts.

Styles opted to keep his shorts on as he took a dip in the water, pulling up the sides to get some sun on his thighs and show off his tiger tattoo.
