Faith Hill reveals that her husband, Tim McGraw, was actually "terrified" about participating in the newly released comedy, Four Christmases. She tells GAC, "For me, I really wanna do a comedy. That's my personality. It would be like breathing for me. But he says, 'I don't wanna do this. I'm scared. I don't wanna do comedy.'" With a little encouragement from his wife, Tim agreed to take on the role and did just fine. Faith shares, "I said, 'You have to do comedy.' Just the script alone – I was on the floor reading it. And then when he got in and started filming the movie, he was great. And I think he surprised himself. That he could actually be really funny." While she really enjoyed watching the film, Hill warns parents that it may not be appropriate for all ages. She explains, "It's kinda raunchy. I'm not sure you wanna take your kids to see it. [It's okay] for older kids, but not your six-year-old that's gonna repeat everything."
