The band's fans jumped onboard and during an interview in Singapore last week it became a subject of conversation, with Calum Hood speaking directly to Derulo via Asia Pop 40.
"Hey Jason, I remember the morning you DM'd me. It was a cold London morning and I was walking into the van and I saw your DM and it just brightened my day," he said. "It just hurts that you haven’t replied."

Then Michael Clifford butted in, saying, "I'm sorry. Calum's my best friend and I just want to let you know, Jason, that Calum's waited every day for the past two years. He's looked at his phone every day and he hasn't stopped -- It's not fine. If you're watching, please have a heart."
Well, from the looks of it, the band got its wish. A couple days later, Derulo send them a message saying, "check your DM's." Now we're all left wondering what they have been talking about.
