Harry Styles and Jimmy Fallon can't help playfully one-upping each other in a new promo for their upcoming Saturday Night Live episode, airing April 15.

The late night TV star (and former SNL cast member) returns to the show for the first time since 2013 on Saturday for hosting duties, with the One Direction singer serving as the evening's musical guest.

Styles is expected to perform his new single, "Sign of the Times," as well as another track off his newly announced debut album.

Interestingly, Fallon and Styles' episode will also mark a historical moment for the long running NBC sketch show: It will be the first time SNL airs live on both the East Coast and West Coast.
