It all started as a joke back in August that 5 Seconds of Summer’s frontman, Luke Hemmings, had a crush on Selena Gomez -- but now he reveals that the gag may have hindered a bromance with Justin Bieber!

The boy band chatted with ET on the red carpet of the American Music Awards on Sunday, where they worried that the jokes about Hemmings’ crush has inhibited their ability to get close to the “Now That I Need You” singer.

“We think that Justin Bieber actually hates us and we’re actually worried that it’s because of this strange rumor,” Michael Clifford, 19, explained.

“I just wanna be friends with Justin Bieber,” Hemmings added, explaining he’d be fine looking past his crush on Gomez if that would help.

Justin Bieber, if you’re reading this just know 5SOS just wants to squash any beef you might have with them!

“We want to cut the beef - we want to slice it into thing thin-cut beef,” band member Ashton Irwin, 21, said.

Over the summer Luke’s fellow bandmates joked around about his big crush on the “Good For You” singer.

"He writes fan mail!" Calum Hood, 19, told ET. "He actually writes poems as well -- 'My Dear Selena.'"

"He has a love shrine in the kitchen!" Ashton joked.
