Jillian Michaels: Gone Girl
"I'm currently reading Gone Girl because all of my friends have been RAVING about it," the world-famous Biggest Loser trainer tells us. "I never read fiction so this is a bit of a stretch for me. I'm about half way through and find it really depressing, but supposedly there's some amazing twist coming that is keeping me hanging on. My friends have great taste, so I'm sticking with it."
