"He said he did, but he would never say otherwise, so I don't know," Fox told while promoting the TMNT reboot (in theaters tomorrow). "He knows better than that—happy wife, happy life! It's his job to tell me I always look really good."

"I liked me as a redhead," she said. "There was one point where it was really red. I was like, 'This is kind of sexy. I really like this red hair.' But it's impossible to maintain."

I'm one of those people when I'm committed, there's no stopping me. So, I did it and after about a week, it repulses me. Like there's bread over there and never again would I put that in my body. But I also don't drink alcohol, which turns to sugar, turns to fat. And I eat a ton of fiber. That's the other thing for women, you really need that fiber."
