Jack Johnson and Jack Gilinsky make up the amazing duo Jack & Jack, but one of the Jacks may be striking it out on his own! Johnson recently announced that he's collaborating on a new track with Sammy Wilk, teasing that they're about to "drop a banger."

Sammy is also very excited about their collaboration together.

The duo wrote it in only an hour, and said that it's a total jam.
Made it in an hour but you'll be jammin to it for hours @JackJ

They even posted some teasers of their collaboration, and it looks like they're having a great time together!
Even though it may seem shocking that Jack is working on stuff without his #1 collaborator, he can totally work on other projects. Remember when Camila Cabello released a song with Shawn Mendes? (Of course you do. It was epic.) She's still in Fifth Harmony! Since Jack and Sammy are both involved, we know their track is going to be great — and we hope that Gilinsky loves it too.
