5SOS 'So Excited' To Play A 'F--king Stadium' With One Direction

5 Seconds of Summer kick off their opening act gig in Dublin, Ireland.

Heading out to see One Direction's Where We Are Tour? Well, get ready because you're in store for an "absolutely epic" show.

On Friday (May 23), the guys kick off the second leg of their stadium tour in Dublin, Ireland, and they're bringing along some familiar faces: 5 Seconds of Summer.

The "Don't Stop" rockers will be joining 1D for the second time on tour -- they opened for them on the Take Me Home Tour in 2013 -- but the Aussies are just as excited as the first time around and still a little in shock that they're playing to such massive crowds.

Ashton took to Twitter to express his anticipation about taking the stage and thank "the lads" for such an amazing opportunity.

The Australian foursome admitted to MTV News back in March that although they expect the tour to be "an amazing time" they "might get incredibly nervous" the first night out on the road. But no matter what happens, they know 1D have got their backs.

“They are really sweet guys and they support us so much and hopefully they let us support them back,” Ashton told us. “We have nothing but good things to say about them; they are such hard working [guys].”

The North American leg of the Where We Are Tour kicks off August 1 in Toronto, Canada.
