NEW YORKOne Direction knocked a major milestone off their bucket list on Saturday night when the guys took the famed stage of "Saturday Night Live" to perform. It was the first time anything resembling a boy band played the show since Valentine's Day 2009 when the Jonas Brothers were the show's musical guests.

For a band whose chart-topping album is called Up All Night, it wasn't difficult for the guys to spend the night wooing fans and non-One Directioners alike with their tracks "One Thing" and "What Makes You Beautiful." The appearance proves that the guys have truly been embraced by the American public.

MTV News was on set with the guys days before their episode aired and got a sneak peek at what the fivesome would be up to come show night. In addition to crooning their way into sleepless Americans' hearts, they also got to shimmy their way through a talk-show-themed skit with host and "Modern Family" star Sofia Vergara. They played the actress' five kids, who learn that their father is sleeping with her incarcerated mother, whom she just met for the first time.

"I think a lot of it is gonna be a big adrenaline rush," group member Harry Styles told us during rehearsals. "The show's so big over here. I think it's going to be a lot of fun and I think we're gonna have as much fun with it as we can."

Niall Horan noted that the guys loved appearing on the show because they really do enjoy goofing around. "This is our kind of show," Horan told us on set, in between rehearsals and photo shoots. "You know, we like to have a bit of a laugh. This is our perfect kind of show [and] we get involved as much as we can."
