"Don't Slack" arrives after last month's Timberlake and SZA collaboration "The Other Side".

Speaking about the collaboration to Zane Lowe on his Apple Music Beats 1 show, Timberlake said, "I hope he doesn’t mind that I’m gonna say this right now, but we talked about a possible joint project. We talked about it, but yeah, he’s a busy man, too. I told him as well, I was like, 'You need to enjoy your moment, bro.' He played me new stuff the other day. That dude is so gifted. He’s so good."

Kelly Clarkson, Mary J Blige, and George Clinton are just some of the collaborators due to feature on Timberlake's Trolls World Tour soundtrack.

In the same interview with Zane Lowe, Timberlake also mentioned he has an unreleased song with Lizzo, "Lizzo, can we please put the song out. We have one. Can we please put the song out? Shout out to Lizzo. It’s like a Chicago house record. And it goes so hard. It’s so fun. It’s so good."

.Paak's feature on Timberlake's new track is his first since linking up with Mark Ronson last year for Spies In Disguise track "Then There Were Two".
