Camila Cabello appeared on the popular US show Tonight Show Starring Jimmy Fallon, which aired last night (Sept 25) at 11:35pm ET/PT on NBC.

The 20-year-old singer-songwriter sat down for a chat with host, Jimmy Fallon, before later taking to the stage to perform her chart-topping single, "Havana," feat. Young Thug. The hit has made history by incredibly being streamed over 100 million times.

During the interview, the Cuban-born American star poked fun at herself with Jimmy about her first audition actually being for The Little Mermaid in 5th grade. She explained that she ended up playing the role of shark number two but entered the stage at totally the wrong time. She also chatted about her love of sushi, her supportive grandmother, and her Latino roots.

The legendary Queen of Pop, Madonna, also appeared on last night's show.
