Making waves! A crew member gets a little too close to a charter guest in Below Deck Mediterranean's Tuesday, May 17, episode, as seen in Us Weekly's exclusive sneak peek.

The Bravo series' footage shows Ionian Princess crew member Danny Zureikat flirting with a visitor as they relax on the beach.

"I could kiss you right now, but I don't think I'm allowed to," he tells her. He later says to the camera, "I know I shouldn't be doing this, but I got butterflies, and the last time I got butterflies was like high school."

Danny and his new friend eventually duck behind some rocks to start making out, but fellow crew member Jen Riservato isn't pleased by what she sees.

"Un-f--king-believable," she tells the camera about her costar's behavior.

Watch the flirtatious scene unfold in the video above.

Below Deck Mediterranean airs on Bravo Tuesdays at 9 p.m. ET.
