With the pressures that come with being on a reality show, there is nothing Vicki Gunvalson won’t try to maintain her figure.

“Part of the problem with being on TV is you’re critical of yourself,” the Real Housewives of Orange County star, 53, tells PEOPLE. “I want to look as best I can, so if it takes plastic surgery, dieting, working out or whatever, I will do it.”

Gunvalson has had a breast augmentation, nose job and chin job, in addition to the tummy tuck she had more than 15 years ago after having her two children.

“Having children definitely takes a toll on the body,” says Gunvalson, who makes sure to get an hour workout like running or weight training into her schedule everyday. “As you grow older and you want to look your best, you do what you have to do.”

The reality star – who was unhappy with the first clip from the new season, which premieres June 8 on Bravo – also says Botox and fillers are not out of the question.

“I try to do it very minimally, though; I don t want to look like a plastic Barbie doll,” she says. “I’m all about trying to look as natural as possible.”
