RHOC Season 19 Reunion Trailer, Air Date, Spoilers, Details

The Real Housewives of Orange County Season 19 reunion trailer is here, and Andy Cohen is about to drop a bombshell that leaves the ladies’ jaws on the floor.

The above sneak peek kicks off with Andy making the unexpected reveal to cast members Shannon Storms Beador, Heather Dubrow, Katie Ginella, Tamra Judge, Gina Kirschenheiter, Jennifer Pedranti, and Emily Simpson, along with friend Gretchen Rossi.

“Well, you guys have seen all of the episodes, but not the aftermath,” he cryptically states. “We wanted you to watch this for the first time.”

As the women look on in a state of shock, a clip rolls showing a stunned Gina, Jenn, and Shannon on a call as a disguised voice on the other end says, “Tamra told my friend that you and she were plotting against Gretchen.”

That could account for why Tamra appears to be in the hotseat with several of her castmates throughout the sneak peek.

“Tamra, that’s f–ked up!” Gretchen tearfully remarks, prompting Tamra to fire back, “You’re making up f–king lies like you’ve been doing to me for so long!”

Later, Gretchen further claims, “I spent thousands of dollars getting a cyber analysis on these posts. A lot of accounts were tied to Tamra.”

While Andy reacts with an “ooh,” Katie adds, “This is insane.”

Shannon, for her part, chimes in, “You’re Tamra Grudge. You have all the grudges.” In another moment, she declares, “This is life changing.”

Meanwhile, after Tamra appears to tell Shannon to “shut up,” she asks someone, “Why do you have to be an asshole?” to which Emily fumes, “You wanna talk about an asshole all the time? That’s you!”

Katie Ginella clashes with Jennifer Pedranti at the RHOC reunion

After deciding to “walk away” from the group midseason, Katie marks her return by unpacking her intense feud with former bestie Jenn at various points in the trailer.

“I’m in the same seat you’re in, Katie,” Jenn tells her in one moment, to which Katie, who’s joined by husband Matt Ginella, replies, “So, I f–ked with your paycheck?”
