5 Seconds of Summer suffered a "traumatizing" experience on their last tour, when One Direction's Harry Styles pulled the ultimate prank on the guys, which involved throwing fruit and being naked.

As crazy as that sounds, it luckily didn't scare 5SOS away, since they've been joining them once again as the opening act on their Where We Are Tour.

So, has Harry stripped down again?

"No, naked Harry Styles, which is a bit disappointing," Ashton said during "Live From MTV." "It's a decrease of nudity on the tour this year."

But that's not the only thing that's different this time around. Since their first go-around with One Direction, 5SOS have become international superstars, releasing their debut album, earning their first Video Music Award nomination and landing a coveted live VMA performance spot on August 24.

"I think it's been different in a few ways, we got to go to Europe for the first time and without them [One Direction], we would have never gotten to meet some of the fans, so that was incredible," Ashton said of the Where We Are Tour. "There's a few more people singing along to our songs, which is nice. That's just a beautiful thing."

One thing that probably won't come out of this tour is a One Direction-5 Seconds Of Summer collaboration, since it's not something their fans would like to see. When asked if the guys would ever team up with One Direction, the 5SOSfam in the MTV audience were quick to boo the suggestion.

"We are two completely different bands," Calum said before Luke added. "We might write with them at some point. If we were going to do a song it'd be with someone that's cool and up-and-coming."
