RHOC's Shannon Beador and Alexis Bellino Face Off in Shocking Season 18 Trailer

Season 18 of The Real Housewives of Orange County will not be sweet and sunny for Shannon Beador.

That's because between her DUI arrest last year and her ex-boyfriend John Janssen moving on with returning costar Alexis Bellino, the 60-year-old is facing a boat load of drama.

In fact, as the Bravo series' newly released trailer teases, Shannon and Alexis have an explosive confrontation over Alexis' new romance with the businessman. 

"I have your ex-boyfriend," Alexis yells at Shannon in the June 6 preview. "There's the door, Shannon Beador!"

The bad blood between the castmembers goes from bad to worse as Alexis seemingly threatens to uncover a secret about Shannon. "We never wanna take someone down like this," Alexis says through tears. "I'm telling you it will ruin her life."

Cut to Shannon, in tears, saying of John, "He's a monster," before Alexis is shown crying and saying, "She's such a piece of s--t!" 

And when Alexis reveals her intentions to eventually marry John, Shannon explodes in a confessional with, "Does she want to be me?!" while also warning of her ex, "You have no idea about John Janssen. You have no idea."

As for what potentially damaging undisclosed info Alexis is hinting at, Shannon is seen calling the supposed rumors "extortion and blackmail."

But her feud with Alexis isn't the only stress Shannon is facing. After she was arrested last September and charged with hit and run while driving under the influence in Newport Beach, costar Tamra Judge is seriously questioning Shannon's life choices.

"Shannon is not taking accountability for what she did," Tamra admits before confronting Shannon and telling her, "You decided to drive your car into a house drunk!"

Alexis even weighs in on the DUI drama by adding, "There's a lot more, and if she wants to go to-to-toe, I'm ready."

Meanwhile, new season 18 Housewife Katie Ginella wastes no time starting beef with Heather Dubrow

"You lied," Katie tells Heather, who viciously fires back, "Stop saying the word lie. I didn't lie!"

However, Katie adds in a confessional, "I can see straight through her."
