5SOS and All Time Low's relationship knows no bounds, and we bloody love it. Whether they're fangirling over each other or recording tracks together, we're secretly hoping 5SOATL will one day be a thing.
Now, though, Michael Clifford's revealed that Jack Barakat broke the boys' 'number one rule' on tour. Was it that you never, ever poke Ashton with a drumstick in his sleep? That humming 'Heartbreak Girl' is off limits? That you must greet Luke Hemmings in a penguin stance (fetus) ever time you see him? Um, not quite.
Chatting to Alternative Press, Mikey said: ""Since then, we've got to know the guys really well and we've had our fair share of adventures with them. Jack [Barakat] even came out on the road with us in summer 2015. I'm pretty sure that he's been touring for about 10-ish years now, so you'd think he'd know the number one rule while on the road: Don't shit on the tour bus.
"What does he do? He shits on our bus. If that doesn't deserve Artist Of The Year, I don't know what does."
There are obviously no hard feelings, though. ATL recently told Maximum Pop they're BFFs with 5SOS 'cos they're so enthusiastic, saying: "The whole thing about bands like 5 Seconds and The Vamps and the younger generation of pop rockery stuff is that they're just so excited to be around bands that they grew up listening.
"They're so fun and they're not jaded, and I'm not saying that we are, but it's refreshing to be around bands that are so young and successful. It makes us feel more energetic and breathes new life into us."
