Brett Eldredge proves he's a Cubs fan for life!

There is no bigger Cubs fan in country music than Brett Eldredge! He shared a video of himself singing the 7th inning stretch over the years... starting when he was just a young kid, up until singing at Wrigley Field last year!

Brett captioned the video: This is me, day one, up to now! Believe in your team from beginning to end...and I mean the very beginning... @cubs #flythew
