Taylor Swift is keeping the guys in Rascal Flatts young. The teen superstar is opening for the trio on their Bob That Head tour, and according to Flatts' bassist/piano player Jay DeMarcus, her electric stage show has inspired them.

"It's neat for us to see somebody as young as she is have such an energy and zeal for the music business," DeMarcus tells Dial-Global. "It kind of has re-energized us to be real honest. To have somebody out there before us kicking our butts every night and challenging us to go out there and be the best that we can be is a really great thing to have."

"He's trying to say she's like our shot of Botox," adds guitarist Joe Don Rooney.

The Bob That Head Tour continues through September. See tour dates on Tourtracker.com.
