Shannon Beador isn't hiding her weight anymore.

The "Real Housewives of Orange County" star took to Instagram to weigh in on her weight gain.

"So let's just get to it. Yes, I have gained weight. A lot of weight. About 40 pounds to be exact," she captioned a recent photo of herself. "I have not had plastic surgery or fillers, it's just plain and simple weight gain."

Shannon said that "multiple factors" contributed to her weight gain and that everything will be addressed on the upcoming season of "Housewives."

"Gaining weight and trying to take it off is a struggle that most women will face at some point in their lives," she wrote.
