It's wild to think about, but it has indeed been four years since Justin Bieber rolled out his excellent fourth album Purpose. Though a recent return to the spotlight has included suggestions from Bieber himself that new music isn't exactly imminent, that wait definitely appears to be in the early stages of coming to a merciful end.

In fact, Bieber was a surprise guest during Ariana Grande's weekend 2 headlining set at Coachella Sunday night.

For the Indio appearance, Bieber pulled Purpose cut "Sorry" out of his big bag of hits. Before leaving the stage, Bieber thanked Grande for the opportunity and provided a quick update on new music.

"Anyways, this is my first time on stage in, like, two years," Bieber told the crowd. "So I had to get my groove back, I had to get my swag back, you know what I'm saying? Thank you so much to Coachella. Thank you so much to Ariana Grande. And we love you so much, man. Thank you so much again. And by the way, album coming soon."

If you missed the moment in person, catch some tweeted footage of it below:

After the performance, Bieber carried the gratitude over to tweets, again thanking Grande. "That felt right," he said.

According to Grande, a lemon also made a surprise appearance during the set. "One of y'all threw a lemon at me," she told the crowd. "Shit."

The previous Coachella 2019 weekend, Grande brought out Nicki Minaj, members of *NSYNC, and more.
