Watch Camila Cabello, Jimmy Fallon & The Roots Perform 'Havana' on Classroom Instruments

She may be the hottest thing in pop right now, but Camila Cabello isn’t too cool for school. 

Cabello dropped by The Tonight Show studios for a performance of her international hit “Havana” with classroom instruments.

The pop artist tackled the lemon shaker and took lead vocals; her host Jimmy Fallon tried his hand at the wood block, bass drum and Casio keyboard; and Questlove looked at ease on the hand clappers.

The former Fifth Harmony singer should be laughing it up right now. Her debut album Camila dropped last Friday and it's poised for a big splash on sales charts around the globe. In the U.S. and the U.K., its challenging the current leader, The Greatest Showman, for top spot on the respective albums charts.
