Jennifer Lopez: PEOPLE’s Most Beautiful (Photo)

Jennifer Lopez graces the cover of PEOPLE’s Most Beautiful issue.

The ‘American Idol‘ judge tells the magazine that she prefers to be makeup free and low maintenance.

“That’s when I’m my happiest,” Lopez explains. “Just being able to touch my face and rub my eyes and put my fingers in my hair and not having to worry about messing it up. It’s so much better.”

But she knows that being beautiful comes with her job description. “The thing is, it’s part of my job.”

“I don’t want anybody thinking it’s easy. It does take time and it’s hard work. HDTV wide-screen is nobody’s friend!” she adds.

Her daughter Emme enjoys a little primping just like mom. “She is very girly-girl, just like me since I was very little. She loves for me to paint her nails. She lays out her clothes on the floor like I do with my stylist and she’s like, ‘This matches very good!’”

But Emme doesn’t have all the fun. “[My son Max] wants to paint his nails too. Because for him, it’s just paint. He’s like, ‘I want the blue!’”

The singer-actress turned reality star admits she has grown into her “diva” label. “I kind of like it. We’ve kind of owned it now. But I certainly don’t like and I’ve never been a person who has what they call ‘diva behavior,’ which is something they tried to pin on me for a long time.”

Who else made the issue?

Teen heartthrob Zac Efron is on the list, with newlywed Reese Witherspoon, Jessica Simpson and Mandy Moore.

Yeah, Jessica Simpson made me blink too.
