If you need another example of how TIM MCGRAW and FAITH HILL are the most annoyingly awesome celebrity couple . . . we've got you covered. Faith turned 50 yesterday, so Tim posted this message on Instagram.
"Happy birthday to the most beautiful girl in the world. You are the most remarkable person that has ever been in my life.
"Our daughters could not have a better role model. I am truly in love with you more every day. Can't wait to see what 'the rest of our life' has in store for us."
"The Rest of Our Life" was in quotes, because it's a song on their upcoming duets album.
