NeNe Leakes admits she's something of a perfectionist.

And now, the Real Housewives of Atlanta star is opening up in the new issue of PEOPLE, on newsstands now, about the lengths to which she's gone for perfection.

"I'm very comfortable and confident in myself. I just wanted a tune up," says Leakes, 42, admitting that in April she got a nose job, smaller breast implants and a lift, as well as liposuction around her waist for contouring.

But Leakes says she didn't want a total transformation. "I still wanted to look like NeNe, the black woman that I am," she says, "but a better version."
