It's a BIG day for 5 Seconds Of Summer fans, and we mean HUGE.

Not only have the Aussie band announced their UK tour dates for 'Sounds Live Feels Live', but they also performed a surprise gig as part of Radio 1's Live Lounge.

Someone pass us a cold towel.

Let's start with the tour, which will begin April 2016 and stop by venues such as London's O2,The SSE Arena in Glasgow and Dublin's 3Arena.

"We are going to try and make this tour even better than the last and the best live show possible for you guys. This is such a huge thing for us to be able to come and see you all," they said of the gigs.

"We can't wait to play you the new album and loads more, we love you guys and hope you are as excited as we are."

While the boys also stopped by Radio 1 this morning, where they announced they'llbe playing at the Teen Awards later this year.

Oh and they covered Bring Me The Horizon's 'Drown' with actual violins and everything.
