Machine Gun Kelly, aka MGK, is best known for his singing — but it turns out he also has a hidden talent.

Appearing on The Tonight Show, MGK explained some of his more confusing social media posts to Jimmy Fallon, ending with one in which he wrote "growing up, jim carrey was dad."

Judging by what follows, this clearly means that he watched the actor's movie catalogue a whole lot growing up, to the point that he can now do an uncanny impression of Carrey in character as both The Grinch and Ace Ventura.

Trust us, it's more impressive than you think it'll be.
