Tim McGraw recently sat down with Oprah for her new show. The premise of the show is to tell the stories you've never heard from the people you thought you knew best.
Apparently, Tim and Oprah had a "very emotional" conversation where he revealed a major secret. What could it be, though? It's killing me! We already know about the secret he discovered at age 11, when he first learned his biological father was the Philadelphia Phillies pitcher, Tug McGraw.
