Carrie Underwood posted a sweet message on Instagram to her daddy yesterday (6/17). She wrote with a picture of her father on her wedding day, "Happy Father's Day to this handsome fella! You think I'm strong. You think I'm fearless...even when I'm at my weakest. You always see the best in me when I can't. I wanna be the girl you think I am. Thanks to all the men out there who lift their little girls up and think they can do no wrong. Thanks to the ones who protect and provide. Thanks to the ones to work hard. You are the first loves of your little girls' lives! Thanks, Dads!"
