Vicki Gunvalson Vomited Multiple Times Before 'Real Housewives Of Orange County' Reunion (VIDEO)

The explosive "Real Housewives of Orange County" Season 8 reunion kicked off Monday night on Bravo, and Vicki Gunvalson, the longest-tenured cast member of the series, admitted she was particularly nervous this year.

"Going into the reunion, I'm always a little nervous as is everybody else," Vicki told OK! Magazine in a video interview (above). "The night before, I didn't sleep ... Getting ready to get on set, I vomited three times -- physically vomited -- and I didn't even have any food in my stomach. I was just so nervous ... about what was going to be happening the entire day."

Vicki told OK! that the "RHOC" Season 8 reunion took "12 hours of hell" to film, and after seeing the first of the three-part reunion, she had good reason to be so nervous. Former cast member Lauri Waring returned after leaving the show in Season 4 and dredged up some of Vicki's dirty laundry.

"This basically all comes down to a few factors: hypocrisy and fame-whoring. And everyone to some extent on this (or any) cast is guilty of these very America-circa-2013 crimes. But some transgressions (Gretchen flirting about while her husband languished with inoperable cancer) are deemed more damning than others (Vicki's maybe/maybe not three-way or twelve-way or whatever)," HuffPost blogger Heather Wagner noted of the Vicki-Lauri showdown. "The point is, nobody is innocent, and everyone makes mistakes, and as much as we'd like our lives to be cleanly edited with no screw-ups or poor choices, these women's lives are edited to heighten their every misstep and make everything as 'dramatic' as possible."

The Season 8 "Real Housewives Of Orange County" reunion continues Mondays at 8 p.m. ET on Bravo.
