The 5 Seconds of Summer guys not only stopped by the Tonight Show to perform, they also helped host Jimmy Fallon out with one of his hashtag segments. Brilliant.5SOS performed "Good Girls" and it was amazing, of course, but their Tonight Show hashtags bit for #FallSongs was too funny. We only wished they had more songs than the handful they were given.
Jimmy sent out the call for the #FallSongs hashtag earlier, having Twitter users chime in with fall-related lyrics to songs, which the 5SOS guys did a bang-up job singing. Our favorite? When they stumbled on switching up the lyrics to their own song. Cuties.
But that's not all - the guys also talked about their first albums in a special Tonight Show web exclusive.
