Any time Justin Timberlake hints at dropping new music, everything stops, but when he links up with Pharrell, it’s certainly something to be worked up about. JT and Skateboard go way back to Timberlake’s debut album, Justified, which Pharrell produced in its entirety. Jutified has since sold over 10 million copies worldwide, and has become the gold standard for just about any member of a boy band or R&B/Pop group looking to go solo (cough, cough, Zayn Malik).

Since then, Timberlake has done extensive work with Timbaland, who produced Timberlake’s next three albums, FutureSex/Love Sounds, and The 20/20 Experience parts 1 and 2 almost in their entirety. Still, Timberlake has continued to work with Pharrell, teaming up with the producer for an unofficially released Game single a few years ago, and an appearance on Pharrell’s G I R L album in 2014. So, yesterday, Timberlake decided to stir the social media pot just a bit, and tweeted out a photo of him and Pharrell in the studio, meaning they could be working on anything from P’s next album to JT’s. Whatever it is, expect reactions like Tyler The Creator’s from fans all over the world.
