Mary-Kate and Ashley Olsen give rare interview about their lives out of the public eye

Mary-Kate and Ashley Olsen, now 30, are opening up about their lives away from the public eye in a rare new interview with The EDIT magazine.

The designers of The Row and Elizabeth and James revealed to the fashion magazine that they're more comfortable these days behind the camera and not in front of it, off social media instead of on it and talking about their design process and not about their private lives.

"We're used to being on the other side of the camera and managing the process, so it's hard for us to do photo shoots now," Mary-Kate says. "That's why you have models."

The twins, who were once the most in-demand movie stars in the world, retreated from celebrity culture around the time they were in college at NYU. Since then, they've ceased starring in films and, instead, have focused exclusively on their successful fashion brands. Because of that shift in focus, the Olsens rarely talk about their private lives.

"When we were younger, being in the public eye was almost part of our role and responsibility -- to set the trends at the time or be ahead of fashion," says Mary-Kate.
