Kaley Cuoco-Sweeting opens up about her decision to get breast implants when she was just 18 years old in the new issue of Cosmopolitan magazine.

Newlywed Kaley Cuoco-Sweeting became a household name during her time on 8 Simple Rules , but the star was hiding a big secret: her recent plastic surgery. Cuoco-Sweeting graces the cover of the May 2014 issue of Cosmopolitan magazine, and talks about her decision to go under the knife at age 18. The Big Bang Theory actress says she has never regretted her choice to get implants, and refers to the surgery as "the best decision I ever made," reports E! Online .

Cuoco-Sweeting also admitted to reading negative comments about herself on the Internet, something that most celebrities claim they never do. "I started reading [the social media comments] and thought, Maybe I need to make more of an effort and not go out in my UGGs and be disgusting. So I started putting on makeup," says Cuoco-Sweeting, but then found that her efforts didn't stop the criticism. Instead, bloggers made fun of the actress for being too styled while out and about. "I couldn’t do anything right. Why am I reading this stuff? But I’m obsessed. I openly admit to being totally insane about that." It's refreshing to read that a celebrity gets self-conscious like everybody else!
