Justin Timberlake set the mood for the 89th Annual Academy Awards and it was a happy one.

The former *NSYNC ring leader opened the show with his Oscar-nominated track "Can't Stop the Feeling" from the animated hit "Trolls."

The crowd-pleasing Timberlake even included a mini-Mouseketeer reunion with Ryan Gosling as he hugged the "La La Land" actor while dancing his way to the stage.

Cameras panned over to proud wife Jessica Biel as she clapped and sang along.
