Why He's Hot: Scotty McCreery will be celebrating his 20th birthday a little bit differently than most people his age. Just six days after he officially leaves his teens, the North Carolina native will release "See You Tonight," his sophomore follow-up to his platinum 2011 debut "Clear As Day." McCreery continues that hot streak in 2013. The first single and title cut from the new disc moving up the singles chart, and he also headlined his first tour this year. That, along with an endorsement deal with fried chicken chain Bojangles, adds up to another year for McCreery on our 21 Under 21 list!
