Justin Timberlake and Anna Kendrick just performed the duet of your dreams.

After a screening of select footage from their upcoming film Trolls, Timberlake, 35, and Kendrick, 30, took the stage to surprise one Cannes Film Festival audience with a special musical performance. The two sang a cover of Cyndi Lauper’s hit “True Colors” from the film’s soundtrack.

“We are Anna and Garfunkel,” Timberlake joked as he introduced the pair. “Okay, we are going to give this a go but you guys have to be nice, okay?”

Before they began singing, Kendrick joked about how nervous she was for the performance.

“This isn’t like a big deal,” she quipped. “We’re just hanging out in your living room and this isn’t a big deal, right?”

Timberlake strummed a guitar with the help of a backup player as both he and Kendrick sweetly crooned an acoustic version of the ballad.

The pair lend their voices to Trolls, which follows the troll princess Poppy (Kendrick) and Branch (Timberlake) as they embark on a journey together.

Gwen Stefani, James Corden, Russell Brand and Zooey Deschanel are also among an impressive list of stars who voice characters in the film.

The 2016 Cannes Film Festival runs from May 11-22. Trolls hits theaters Nov. 4.
