Hannah Berner and Paige DeSorbo's friendship gets put to the test on "Summer House."

In a sneak peek of the upcoming episode from ET, the best friends get into one of the biggest fights in the Bravo series. As fans of the show know, Luke Gulbranson and Hannah have been dancing along and blurring the lines of friendship, relationship, and hook-up, but not everyone is a fan of the potential budding romance.

After a whole summer of learning about Luke's blatant lack of honesty -- (i.e. hooking up with and dating other girls) -- while still trying to pursue the 28-year-old podcaster, Paige, who along with Amanda Batula has been vocal about their distaste for the new cast member's actions, try to have a conversation in hopes of talking some sense into their friend. However, Luke is a topic that three women can't seem to agree on.

"You guys actually don’t know Luke, and you don’t understand me and him. This whole time I’ve been good. Do you guys even [expletive] know Luke? No. You’re sitting back, you’re not out with us… you guys, I’m not dating him!" Hannah says in an attempt to defend her situation with Luke.

"Because he played the [expletive] out of you!" Paige claps back. "How do you not see that? He’s been [expletive] girls all summer. He’s been manipulative to you. He came up to you at a party and said, 'Don’t talk to a guy in front of me!'"

Hannah continues to try to get her point across by explaining that she's "never been with a guy who wants to talk to me all day and not have sex with me, and now I realize it’s because he had feelings and didn’t want to [expletive] it up."

"That’s an insane excuse. If you have feelings for someone, you have sex with them!" Paige jeers.

"I lost an entire [expletive] summer with you because of him! Hannah, I missed you all [expletive] summer ... I did this summer to hang out with you," she adds as she's on the verge of tears.

While this is all happening outside by the lavish pool, the rest of the "Summer House" cast -- Carl Radke, Lindsay Hubbard, Kyle Cooke, and Luke -- watch everything go down from the safety of the house.

Eventually, Lindsay steals a tearful Hannah away as Jules Daoud, a new addition to the Season 4 cast, consoles Paige as she cries and claims she doesn't want to fight.

The new episode of "Summer House" airs Wednesday at 9 p.m. EDT on Bravo.
