The 23-year-old singer is set to make his first solo television performance during Saturday’s episode (April 15) with host Jimmy Fallon.
The duo teamed up to film some hilarious promo videos for their episode but they just couldn’t keep it together!
While trying to stay serious and get up close with camera, Harry couldn’t help but burst into laughter.
Harry and Jimmy‘s episode will also be the first time that SNL simultaneously airs the show on both coasts at 11:30 PM EST/8:30 PM PST.
