Ariana Grande was all smiles as she appeared on The Tonight Show Starring Jimmy Fallon last night.

During her appearance on the show, the singer decided to play a game with host Jimmy Fallon called, “Best Friends Challenge” (because obviously these two are the best of friends) and the results were nothing short of hysterical.

Aside from Ariana’s hilarious revelation of choosing to be a seahorse over any other animal in the world, the “Dangerous Woman,” singer also shared the surprising identity of her first ever celebrity crush.

So who’s the mystery man young Ariana had a crush on? It was none other than actor, Jim Carrey.

The answer seemed to totally shock Jimmy, who thought he was the singer's first crush and Ariana's reaction to the mixup was nothing short of hilarious.

Ariana's answer totally took us by surprise too. We had no idea she had a crush on the comedic actor.
