Exclusive Behind-the-Scenes of RHOC Season 18 Reunion: Andy Cohen Teases Aftermath, Seating Chart Revealed, Plus Jenn & Tamra’s Pre-Filming Moments and Gina’s Reaction to Leaked Photo with Emily

The cast of The Real Housewives of Orange County gathered to film their much-anticipated season 18 reunion on Sunday, giving fans a sneak peek into their big day through social media.

As Watch What Happens Live host Andy Cohen, 56, shared behind-the-scenes snaps and cast members Jennifer Pedranti, 47, and Tamra Judge, 57, posted pre-show updates, Bravo officially revealed the seating chart, and a leaked image of Gina Kirschenheiter, 40, and Emily Simpson, 48, quickly circulated online.

On October 6, from the RHOC reunion set, Andy teased fans with a glimpse of the action, posting an Instagram Story of his cue cards lying on the tiled floor. Jennifer, en route to the reunion, shared a selfie from inside a car, captioned, “Big Day!”

Over on Bravo’s Instagram, the highly coveted seating chart was revealed. Shannon Beador, 60, and Tamra Judge scored the prime spots flanking Andy, with Shannon seated to his left and Tamra to his right.

To the right of Tamra, filling out the couch, were Gina, Jennifer, and Katie Ginella, 40, sitting in order of proximity to Andy. To his left, Emily, Heather Dubrow, 55, and Alexis Bellino, 47, completed the lineup.

Despite only being a “friend” in season 18, Alexis’s relationship with Shannon’s ex, John Janssen, 61, and the drama surrounding it earned her a more prominent role in the reunion, extending her appearance beyond a typical friend cameo.

Tamra Judge also took to her Instagram Story, giving followers a behind-the-scenes look at her reunion prep. In a post from her trailer, she posed with her glam team, writing, “Let’s do this…” followed by, “The best glam in the OC.”

Meanwhile, Gina addressed the accidental leak of a photo of herself and Emily. Taking to Instagram, she explained to her followers what had happened and teased a more flattering photo to come.

“Okay, I’m exhausted,” Gina began. “I just got home from the reunion, and I know there’s already been a picture of Emily and me posted. It was an accident. It was Emily’s glam person. I wasn’t thrilled, but I just want to let you guys know — if you could forget that happened, that’d be great! Bravo’s going to release another photo, which I probably won’t like, but then I’ll share the one I think I look best in. And if everyone could just judge me off that one, that would be ideal. That’s all!”
