T-Pain Sings the U.S. National Anthem Without Autotune

The Grammy Award winner showed off his pipes in front of a packed stadium on August 31.

T-Pain performed The Star-Spangled Banner at the Dodgers vs. San Francisco Giants’ game in Los Angeles without the help of autotune -- and it sounded beautiful.

Stunned fans took to Twitter to congratulate the 30-year-old on his performance.
