Disney star Demi Lovato proved she is firmly on the road to recovery when she took to the field at the World Series game in Arlington, Texas on Monday to sing the national anthem, and RadarOnline.com has video of her impressive performance.

The recently rehabbed teen nailed the patriotic song as she belted out the Star-Spangled Banner in front of hundreds of baseball fans (and millions of television viewers) at the Game 5 face-off between the Texas Rangers and the St. Louis Cardinals in her home state of Texas.

Dressed in a red Texas Rangers shirt with matching black shorts and blazer, Demi showed no sign of the nerves during her big-voiced performance, but she admitted to her Twitter followers on Sunday that she had baseball-induced butterflies.
