Mary-Kate OlsenMary-Kate OlsenIf you pop by Mary-Kate Olsen's house unannounced, you may get a surprise.

If her naked chat is anything to go by.

The pint-size star told Harpers Bazaar magazine how she loves spending her free time, saying: "I run around my house naked with heels all the time. It's so funny.

"All my friends will tell you I love running around in kimonos and jewellery or naked with jewellery."

Well, her birthday suit aside, she said of going back to her blonde roots: "I woke up one morning and was like, I want white-trash hair today."

She also chatted about her style, saying: "Sometimes I'll look at people or at a magazine and I'll do a double take because I'm like, 'Oh, my God, that's my outfit, but that's not me.'"

Of being constantly snapped out and about with her sis, Ashley, she reckons: "They take photos of us going into our offices, and it's, 'Mary-Kate and Ashley shopping again.' But I'm going to work for eight hours, and we're working so hard. It just shows how people want to think of you."

Another gem she departed was this: "I feel like I've lived 10 different lives already and I'm only 21. But I also feel like I'm entering a new chapter."

Let's hope it's another page-turner...
