The Real Housewives of Orange County Season 12 cast.

Interestingly enough, Season 8 star Lydia McLaughlin is coming back this year after leaving the show following just one season of drama. No doubt her husband of 10 years, Doug McLaughlin, and their three sons, Stirling, 8, Maverick, 6, and Roman, 2, will pop up at some point.

After she quit, the 36-year-old revealed, “When I was asked back to do Season 9, I wanted to do it. Being on the show was everything the world tells us to desire and it was what I desired. But deep, deep down — so quiet I could almost silence it — I knew in my heart it was not God’s plan for me to go back. I knew God was calling me to walk away from the show."

Now that she's returned, Lydia confirms fans are in for a wild ride. “The first time I could play dumb and say I didn’t know what to expect,” she tells Us Weekly. “But this time I knew what it was like, and I still went for it. I’d describe this season as, 'I’ve lost my mind.'"

We can't wait to watch!
