So it should come as no surprise that on the star's list of things the public will never, ever see her in: track suits and UGG boots!
"You'll never see me on the street in a tracksuit. I just love fashion too much to wear a tracksuit! The same goes for UGG boots. I only wear them only at home," she tells the latest issue of France's Madame Figaro magazine.
"I am a big fan of Net-A-Porter.com," the 37-year-old continues. "When the kids are asleep, I can travel on this site for several hours. I like the idea of quietly shopping at home for clothes and returning them if it don’t work. This is absolute freedom."
