The group are due to perform live on Good Morning America today (September 30) and the Australian said in a Keek video that he is taken aback by playing show huge gigs.

Irwin said: "This morning we're playing Good Morning America. One and/or two songs, and I'm pretty stoked.

"I can't believe we actually get an opportunity like that - and it's all thanks to you dudes. I can't thank you enough. I'm a little delirious because I haven't been to sleep at all, but it's gonna be awesome."

5 Seconds of Summer meanwhile will also appear on Jimmy Fallon's Tonight Show on October 2.

The pop-punks are currently on tour in North America supporting One Direction on their Where We Are stadium run.
