Justin Timberlake and Anna Kendrick's Duet Will Give You Goosebumps

Justin Timberlake and Anna Kendrick joined each other on stage at the 2016 Cannes Film Festival to surprisingly serenade the crowd with some sweet music.

"We are Anna and Garfunkel," Timberlake introduced the duo with a guitar in his hands. "Ok, we are going to give this a go, but you guys have to be nice."

"We're just friends here right?" Kendrick joked. "This isn't like a big deal...we're just hanging out in our living room."
