Is there beef between 5SOS and Justin Bieber?

Yikes- the 5 Seconds of Summer guys fear that Justin Bieber is not their biggest fan! It all started when the guys jokingly said that Luke has a major crush on Justin's ex, Selena Gomez. "We think Justin Bieber actually hates us and we're worried it's because of this strange rumor," Michael says, with Luke adding, "I've only met her once and I just want to be friends with Justin Bieber." So JB, if you're reading this, 5SOS want to end the drama, ASAP! "I know I can't ride a skateboard and I can't pull off long basketball pants," Ashton explains. "But we want to cut the beef!"
