Another Below Deck guest is rocking the boat.
Traveler Kelly gets out of control after boarding the St. David in E! News' exclusive sneak peek at the Bravo series' July 28 episode.
While sitting down for lunch with her friends, Kelly—drink in hand—starts yelling with excitement, much to the annoyance of her fellow vacationers and the season 12 crew waiting on them.
As her friend Brian says in the preview, "A little bit overboard. Kelly, stop! Kelly, zip it."
But as the guests dig into their food, Brian reminds his pal, "Kelly, if you drink less, we can enjoy everything."
Kelly's response?
"Hey, I talk about whatever I want," the seemingly overserved partier claps back, "whenever I want!"
The group's rowdy antics aren't received well by the crew, as Stew Barbara Kulaif is heard complaining downstairs, "Oh my God, these people. Nightmare."
Kelly only wants to keep the party going, as she announces over lunch, "I'm ready for Jack Daniels."
The declaration prompts Chief Stew Fraser Olender to remind Kelly of the team's safety requirements, "If you're really keen to jet ski, you've just got to be aware of how much you're drinking."
She angrily replies, "Oh my gosh, you don't know our tolerance! Like, you have no idea."

However, Fraser responds with, "We can see your tolerance."
But Fraser and Barbara aren't the only yachties who are over the antics.
Stew Rainbeau de Roos reacts in a confessional, "She is, like, shwasted. Like, s--t-faced. She had to be chugging bottles of champagne in the taxi on the way over. She's on a f--king spaceship to the moon."
Kelly doesn't receive the team's feedback. As she requests at the end of the preview, "I'll take more champagne is you have it."
See the drama continue to play out when Below Deck airs Mondays at 8 p.m. on Bravo. In the meantime, keep reading to see more past guests who got a little too out of control.
