shannon beador gained 40 pounds before the start of filming on "The Real Housewives of Orange County" season 12 and during production, her weight gain became quite clear during a cast trip to Iceland. According to a new report, Beador struggled to keep up with her co-stars, especially fitness buff Tamra Judge, as she and the ladies attempted to go for a hike on rocky glaciers.

On October 23, Radar Online shared a sneak peek at the upcoming episode of the Bravo TV reality show with readers and in the clip, 53-year-old Shannon Beador was seen getting exhausted as she panted and stumbled on the terrain.

“Clearly, my exercise regimen has not prepared me for this hike,” Beador explained in the clip, adding that she hiked to the bottom of the mountain before getting winded on the way up.

Kelly Dodd, who joined the "Real Housewives of orange county" cast during season 11 as a friend of Meghan King Edmonds, also struggled to make it up the mountain -- but only due to a couple of surgeries. “I just had a [breast augmentation]... I’m under construction,” Dodd explained. Meanwhile, Tamra Judge mentioned that her co-star had also undergone a vaginal rejuvenation procedure.

As for Judge, she made it right up the mountain without so much as a bead of sweat on her forehead, much to the dismay of Shannon Beador, who labeled her a "show off."

Shannon Beador is trying to lose the weight she gained after 'RHOC' season 11

Ever since the start of the 12th season of "The Real Housewives of Orange County," Shannon Beador has been dedicated to dropping the 40 pounds she gained due to the alleged stress she faced after the 11th season of the show.

As fans may recall, Beador's husband, David Beador, was targeted with claims of abuse from Vicki Gunvalson, who claimed Beador had confided in her prior to their falling out. While both of the Beadors denied the allegations were true, the stress from the allegations impacted the mother of three substantially and now, she is following a strict diet and exercise plan in hopes of getting her body back to what it was prior to season 11.
