If you're a fan of both the Janoskians and 5 Seconds of Summer, you're in for a serious treat. The guys from the Janoskians have teamed up with 5 Seconds of Summer's Calum Hood to produce a new song called "Cloudy."

The guys unveiled the news during an interview with Capital FM where they dropped by to promote their upcoming show, Janofest -- a one night only event taking place on March 21. There's no word yet as to when the track they co-wrote with Calum will be released to the public, what it sounds like or even what the lyrical content is, but according to the Janoskians, "It's been rumored to be the number one single of all time." Sadly, the song was pulled from their EP Would U Love Me, so it might be a little while before the song is released on its own. The reasoning behind taking it off the EP? According to James, the song is kind of a big deal. He said, "It's so huge they want to release it as a single on its own."

As for how they got together to write the song in the first place? The Janoskians have been friends with the 5SOS guys for a while. They said, "We've been mates with [Calum] for a long time, before they blew up. It's just fun times in the studio together, making memories, you know?" We definitely hope the track makes its way into the public sphere at some point in the near future.
