Hilary Duff has come a long way since her days on the hit Disney show, 'Lizzie McGuire.' At 23 years old, she's married, written two books, making movies and whispering about her second album.

"Nothing's set in stone yet, but I really miss recording and I miss being on tour. I'm definitely getting that itch again to get back into the studio," Duff told PopEater

Duff, an animal lover at heart, would be a veterinarian in her other life if she had to do everything over. As far as collaborations go, she's a fan of everyone named Kate. Kate Beckinsale, Cate Blanchette and Kate Winslet to name just a few.

So one has to wonder, if given the opportunity to take Kate Middleton's shoes, would Duff be up for the challenge? "If I were her and I fell in love with someone, and he happened to be part of the royal family, I would definitely get married."

Hats off to you, girl. You don't seem to be afraid of anything.

We caught up with Duff during her Sobe 'Try Everything' challenge in New York City. Watch the video on PopEater after the jump!
