Real Cast Shakeups! 'RHOC' Star Quits Show For 'Simpler Life'

The current season Real Housewives of Orange County is nearly over and RadarOnline.com has exclusively learned that a key cast mate decided to quit the show !

According to a source close to production, Vicki Gunvalson's daughter, Brian Culberson, 30 — along with husband Ryan and two sons, Owen and Troy – are leaving Orange County, Calif. and moving to North Carolina in favor of a "simpler life!"

"Briana is leaving the show but she didn't have a blowout fight with Vicki or anything like that," the source claimed.

"In fact, Vicki is supportive of her decision and understand why they are leaving. They want to raise their family away from the spotlight of Hollywood and they definitely want a simpler life."

"They thought that when they moved back to the O.C. that their life would be simple because it is Orange County!"

"But they cannot go anywhere without being stopped for autographs, or without people talking and pointing at them," the source told RadarOnline.com.

"That is not what they want for themselves or for their family."

As fans know, Briana moved to Oklahoma with her husband after he served in Afghanistan, but the couple decided to move back to the O.C. two years ago, in November 2015.

At the time, Ryan remained in Oklahoma while awaiting his medical retirement from the Corps.

This past season, Briana dealt with some very serious health issues related to her Lupus diagnosis.
