Julia Roberts Is PEOPLE’s 2017 World’s Most Beautiful Woman!

It’s been 26 years since Julia Roberts was first on the cover of PEOPLE’s World’s Most Beautiful issue, and she’s still our favorite pretty woman.

The stunning star is, for a record fifth time, the Most Beautiful Woman in the World – though she can hardly believe it. “I am very flattered,” she tells PEOPLE’s editor-in-chief Jess Cagle in this week’s cover story.

Roberts, 49, opens up about her happy 14-year marriage to cinematographer Danny Moder, her life with twins Hazel and Phinnaeus, 12, and Henry, 9, and the secrets of her ageless beauty in her interview with Cagle and PEOPLE’s style and beauty director, Andrea Lavinthal.

She thinks the best is yet to come: “I think I’m currently peaking.”

Roberts was just 23 when she first appeared on the cover of the World’s Most Beautiful issue in 1991. The year before, she had skyrocketed to instant fame when she starred in the smash romantic comedy Pretty Woman.

But behind the scenes, Roberts reveals, she had no idea how much her life had changed.
