On May 1, 1967, Earth was graced with a little more country, thanks to the birth of Samuel Timothy Smith, or Tim McGraw, as the world knows him.

McGraw learned how to play guitar as a student at Northeast Louisiana University (now the University of Louisiana at Monroe). The Delhi, La., native was in school on a baseball scholarship but dropped out in 1989 -- on the day his country hero, Keith Whitley, passed away -- to pursue his dreams of a music career. And he hasn't looked back since: McGraw signed with Curb Records in 1990, struck success with his 1994 record, Not a Moment Too Soon, and has gone on to make a big impact on country music.

The "Live Like You Were Dying" hitmaker is no longer a baby-faced 20-something with long hair and a mustache; now, he's a superstar with an impressive 13 studio albums, three Grammys, 14 ACM Awards and 11 CMA Awards. Plus, he is a father of three, the husband of fellow country star Faith Hill and a self-professed workout maniac, looking more chiseled than ever -- even at the age of 48.
