It looks like Siesta Key‘s no. 1 couple might be falling apart.
In PEOPLE’s exclusive sneak peek at Tuesday’s episode, Alex — the wealthy “king” of the Sarasota, Florida-adjacent island — and his girlfriend Juliette end up in a nasty fight at the bar after he accuses her of being “a brat.”
“You want to walk through the things I’ve done for you today?” he says. “Got you your Starbucks and your bagels, and then went and filled your whole gas tank. Literally, I do everything for you.”
“Alex, you need to stop pinning nice things you do for me on me like I owe you,” Juliette fires back, starting to get emotional. “We’re in a relationship. Why do you have to start tallying the nice things you do for me?”
At that point, Alex’s sidekick/cousin Pauly decides to get involved.
“What do you do that’s nice for him?” he asks Juliette, to which Alex answers for her: “Nothing.”
“I drive every f—ing weekend to see you,” Juliette says, crying.
Chloe tries to intervene, but it’s too little too late — and now Juliette has it in for Pauly.
“All we ever do is with his stuff. It’s Alex, Paul. You use all his f—ing stuff, so how is that different from me?” she says. “What do you ever do for him?”

“She’s like, ‘Oh, I do all this for Alex,’ but she can’t name one thing,” Pauly says, which apparently pushes Alex over the edge.
“Dumba—,” he mutters, before turning to face his girlfriend to call her an “idiot” in front of the rest of the group.
“Do you not see how rude that is?” she pleads. “You love me. Why would you say that?”
Siesta Key airs Tuesdays (9 p.m. ET) on MTV.
