Justin Timberlake and Timbaland are back to doing what they do best -- collaborating!

The "Sexy Back" singer and hit-making producer were seen together in the studio listening to beats in a video Timbaland shared Wednesday to his more than 3.5 million followers on Instagram.

The mega producer captioned the video, "Soon to come," along with a few eye emojis and fireworks.

It's unclear if they were sampling beats for Timberlake's upcoming sixth studio album or

if it's more closely related to Timbaland's new business venture, Beatclub, an online beat-selling marketplace that connects aspiring music creators with mega artists who have joined the digital platform.

"It gets me excited to collaborate with people I've never even met," Timberlake told The Associated Press back in September.

"Even the stuff we're working on right now with my record, it's all Beatclub. It's Tim bringing in people who he's found through his platform and bringing them to me."

In any event, seeing Timberlake and Timbaland in the studio only added fuel to the fire that they're that much closer to not just collaborating again but dropping their next masterpiece sooner rather than later.

Timberlake and Timbaland go way back, as far as JT's 2002 debut album, Justified.
