Kaley Cuoco has opened up about her cosmetic enhancements, insisting she has no reservations about undergoing plastic surgery to change the things she doesn't like about herself.

The Big Bang Theory star admits she got such a big confidence boost following a boob job she decided to go under the knife again to get her nose and neck fixed.

In 2014, Kaley had surgery to correct an issue with her sinuses and subsequently denied nose job rumors, but now she admits she did have work done and recently underwent another procedure on her neck.

"Recently I had a filler in a line in my neck I've had since I was 12," she tells WomensHealthMag.com. "As much as you want to love your inner self... I'm sorry, you also want to look good. I don't think you should do it for a man or anyone else, but if it makes you feel confident, that's amazing."

Fitness is also a huge part of Kaley's life and the actress follows a strict workout and diet regime to achieve her envious physique, which she shows off on the cover of the magazine.

"Bottom line is, you know, I'm not 21 anymore," she says. "It used to be so easy, I didn't have to do as much. Now, it's part of my day - working out is part of my day, eating right is part of my day."

However, the 30-year-old admits that while she enjoys seeing the results of her workouts, she is not always thrilled to hit the gym.

"Sometimes do I want to get up in the morning and do it?" she adds, "but when I get out, I feel like a million bucks."
