Justin Timberlake’s last album, 2018’s Man of the Woods, featured high-profile collaborations with Alicia Keys, Chris Stapleton and Pharrell. And it looks like his next album just got its first collaborator: vocals from none other than Jimmy Fallon.

The Grammy-winning singer catches up (virtually) with his longtime pal on Friday night’s (Jan. 29) episode of The Tonight Show Starring Jimmy Fallon, where they jokingly discuss the possibility of a Fallon feature.

“Listen, I’ll happily put you on a record if you want to be on a record,” Timberlake insists in this preview clip, exclusively on Billboard. “You want to sing backgrounds?”

Jimmy looks off-camera, shocked, before saying (obviously), “Yeah!”

“OK, done,” Timberlake said.

“What? Did this just happen? We can’t edit this out! We have to leave this in the show!” Fallon says.

“But I’m going to treat you the same way that I did right before we did the first Bee Gees sketch we ever did,” Timberlake says of their beloved “Barry Gibb Talk Show” skit on Saturday Night Live.

Watch the clip below to see exactly what that means, and you can watch the full interview on NBC at 11:35 p.m. ET on The Tonight Show, where Ozuna and Anuel AA are the night’s musical guests.
