Rae Sremmurd teamed up with Justin Bieber during a recent Sremm Life tour stop.

So, what does JB do when he's on stage with Slim Jimmy and Swae Lee? Well, he apparently unlocks the swag. The "Where Are U Now" singer joined the MCs for "Unlock The Swag" onstage and managed to dance along to the tune while holding a bottle of alcohol.

In fact, Biebs took a sip from the bottle, poured some on the crowd and passed it around too. Here's a look at how that all unfolded:

He's taking some sips.

And he's pouring some onstage.

He's giving fans some of it.

And he's unlocking the swag.

Fans are clearly loving it.

And the fire emojis are out.

Listen to the song below.

Rae Sremmurd are on tour. They're set to continue their run across the world until Dec. 16 when they land in Dublin, Ireland.
