5 Seconds of Summer have been hitting the road pretty hard this year (as if that comes as any surprise, the Aussie pop-rock band is literally always on tour). They're currently embarked on their second ever world wide arena headlining tour, Sounds Live Feels Live. They've ripped through Asia and the U.K. and tomorrow, they tackle continental Europe. Jet setters, the whole lot of 'em!

With their North American dates approaching, those of us on this side of the pond had to wonder: Who the eff is gonna open for them in America? Today, guitarist Michael Clifford has heard and answered our cry with a tweet.

Labelmates Hey Violet return to open for the guys. They'll be joined by U.K. opener Roy English and Japanese rock band One Ok Rock (the latter of which work with longtime 5SOS producer John "Feldy" Feldmann regularly.)

Figure out who will open for your show in the image above, then take our quizzes: How Well Do You Know 5SOS? and Which Member of 5SOS Are You?
