Demi Lovato On Pre-National Anthem Jitters & Flirty New Single

Before she performed the national anthem during Game 5 of the World Series between the St. Louis Cardinals and Texas Rangers this past Monday, Demi Lovato felt like she was about to jump out of a plane. That’s what the part-Mexican singer/actress told MTV News before belting out the patriotic song at Rangers Ballpark in Arlington.

During her performance, 19-year-old Lovato showed off her Texan pride by sporting a red Texas t-shirt. MTV News spent a day with the star as she prepared for her performance in front of more than 50,000 baseball fans.

Lovato’s performance proved stellar and the teenage star was welcomed with premature cheering. After she left the field, Lovato was approached by fans and athletes, including Dodgers center fielder Matt Kemp, who had also reportedly left the field after winning an award. “I’m like, freaking out right now,” Lovato said once she entered the green room, filled with family and friends.

Lovato also dished shared deets about her second single, “Who’s That Boy. “It's just a fun, upbeat song,” she said. “It's flirty, it's sexy, it's exciting and I love it.” Lovato added that she thinks the song is radio-friendly, and a good choice for a second single. “Who’s That Boy” features singer Dev, who is of Portuguese descent and, just like Lovato, part-Mexican!
