Allie Colleen is the youngest daughter of one of the greatest entertainers in Country music, Garth Brooks. Just like her Daddy, Allie loves to sing and she has an amazing voice (just like her Dad.) She just recently celebrated her 24th Birthday and instead of getting a gift, she gave us one instead. Allie released two new songs, "Best Friend" and "Road You Take." Although she has extremely big shoes to fill when you Dad is Garth Brooks and your step mom is Tricia Yearwood BUT she seems to filling them in very well!
