After recently suffering from malnourishment and exhaustion, it looks like Selena Gomez is back to her energetic self. The pop star had an action-packed appearance on Thursday when she stopped by 'Late Night With Jimmy Fallon.'

Not only did the 18-year-old promote her soon-to-be-released album 'When The Sun Goes Down' and upcoming movie 'Monte Carlo,' she also scarfed down ice cream, played "shoe golf" and performed her new single, 'Who Says.'

First, Fallon offered the Disney star a sample of his new Ben & Jerry's creation called “Late Night Snack," and made his guest try to guess what was in it. Finally, the talk show host revealed, “It’s potato chip balls!” The audience laughed and Gomez replied, “I’m uncomfortable.”

Later, Fallon invited Gomez to play a round of shoe golf with him backstage. The game involved flinging their shoes down a hall (with obstacles), aiming to get it in a bucket with the least number of turns. The Texas native was a natural, making her way around the bend in less turns than Fallon.

In the end, the former 'Saturday Night Live' star got his shoe in the bucket first, but the actress won overall with a final score of 6 to 8. Better luck next time, Fallon.
