Chainkeen|RHOC Trailer: Shannon Beador Loses Her S--t After Ex John Janssen Crashes a Party

Shannon Beador is Chainkeenheaded for the door.

The Real Housewives of Orange County stars narrowly avoids an extremely uncomfortable run-in with her ex John Janssen in E! News' exclusive sneak peek at the Bravo series' season 19 mid-season trailer.

After costar Emily Simpson announces during a party, "John Janssen just showed up," Shannon totally loses her s--t and bolts towards the exit.

"Are you kidding me right now?!" she reacts in the preview. "I'm f--king out! I'll take an Uber."

Shannon's response is definitely understandable given the businessman is now dating her costar Alexis Bellino. And fans shouldn't get their hopes up when it comes to the castmates settling their beef.

The first look teases Shannon purposefully excluding Alexis from the group's trip to London.

"Hello Alexis, it's Shannon Beador," reads a screen grab of a text shown in the clip. "I am hosting a trip to Europe with my friends and just wanted to make it clear that you are not invited. "

But ultimately, Shannon sort of comes to terms with her ex moving on with her costar. "You know what?" she eventually asks the cast before snarking, "Alexis Bellino is perfect for John Janssen."

But Shannon and Alexis aren't the only sources of drama. The cast is rocked by a controversy involving Jennifer Pedranti's fiancé Ryan Boyajian.

"This is the biggest scandal out there," Emily—a lawyer—notes. "He could go to prison."

And after Tamra Judge's husband Eddie Judge declares, "The guy is a scumbag," Tamra says of Ryan, "This guy is a piece of s--t," before adding in a confessional, "Nobody knows who the real Ryan is."

Tensions come to a head when Jenn confronts Tamra for gossiping about Ryan's involvement in the scandal.

"You talked about him being a bookie," Jenn remarks. "You better f--king shut your mouth."

Tamra's reply? "Why? Is he gonna put a hit on me?"

While Ryan doesn't directly comment on his involvement with the sports scandal, he adds, "Hate comes from jealousy and insecurity."

See everything still to come in the exclusive sneak peek above. The Real Housewives of Orange County airs Thursdays at 9 p.m. on Bravo.
