Selena Gomez has a surprising way of getting pumped up before her shows.

The 23-year-old singer revealed she's a huge Big Bang Theory fan on Tuesday, when she Instagrammed a picture of herself watching the hit CBS show on her laptop before her concert in Nashville, Tennessee. In particular, she can’t get enough of the endearing Sheldon Cooper, played by Jim Parsons.

"The one thing that gets me going before anything... Sheldon Cooper -- Big Bang Theory," Gomez captioned the cozy pic of herself wrapped up in a blanket and enjoying a beverage.
