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.

The Texas Rangers baseball team are paying tribute to the man that fell 20 ft to his death at their stadium Thursday night.

The Arlington based ground are flying all of their flags half-mast as a mark of respect to Shannon Stone, who died in front of his six-year-old son in the tragic accident.

Minka and Jeter, who was in town with the Yankees for the MLB play-offs against the Texas Rangers, had just arrived at the Crescent Hotel in Dallas when they walked into a nearby Starbucks.

According to an eyewitness, the couple acted like anyone else, waiting patiently in the long line of customers.

"It looked like they had just arrived because their bus outside was unloading all of their stuff," the insider told RadarOnline.com exclusively.

"They were pretty quiet and kept to themselves. At one point someone yelled out, 'hey Derek!' and he looked really uncomfortable, like he didn't want to be recognized. He kind of turned and gave a half smile, but she kind of laughed and was sweet about it."

Perhaps the baseball star was just anxious about his upcoming game. The eyewitness told RadarOnline.com that Jeter and Kelly, who starred in TV's acclaimed high school football series, Friday Night Lights,  arrived at around 2:15 p.m.---- just a few hours before the Yankees-Rangers game was set to start.

"I was surprised to see them getting coffee so close to game time," the source said. "My mom works for the Rangers and I know that players have to be at the field several hours before the first pitch."

The witness said Minka, who was just voted Sexiest Woman Alive by Esquire magazine, was dressed casually in leggings and a plain top. She ordered "a small coffee" while Jeter "ordered a monster Venti fancy latte drink."
