5 Seconds of Summer tends to have some really elaborate set designs on tour and during live TV performances whether they are for award shows or other TV shows like their performance from Friday morning on Good Morning America.

How Personal Will 5 Seconds of Summer Get On Their Sophomore Album?

All of these elaborate sets are the work of one individual who Ashton Irwin felt the need to thank after he and his bandmates rocked out in Central Park on Friday morning.

Irwin and his bandmates, Michael Clifford, Luke Hemmings and Calum Hood, are constantly thanking the team behind them for all of their hard work and constant support so it's no surprise really that the drummer felt the need to send praise to the set designer.

Would The 5 Seconds of Summer Guys Ever Consider Babysitting For One Direction's Louis Tomlinson?

Emma Bull is the lady behind the Australian pop/punk rockers' sets on stage. Her artistic direction is modern as she combines the performance aspect with fabulous lighting designs and rad art designs (hello, 5 Seconds of Summer's awesome graffiti artwork that is always on display during their gigs).

"[Y]ou've done such a great job on all the sets!" Irwin gushed in a tweet to Bull.

"Thank you for your endless hard work and making our visions come to life!!!!" he added.

Bull graciously accepted Irwin's praise and teased, "the best is yet to come."

We're certainly intrigued about what other amazing sets Bull can create for the Aussies since the ones she has already have been incredible.
