Oscar host Jimmy Kimmel got quite the introduction as Justin Timberlake opened the show with a rousing rendition of “Can’t Stop the Feeling” that got the A-list audience dancing.

Starting outside the Dolby Theatre, where the awards are held, Timberlake sang and danced through the lobby, picking up backup dancers along the way.

He also mixed in several bars of Bill Withers’ R&B classic “Lovely Day.”

The lip-synced performance took the “Trolls” voice actor and former ‘N Sync member up onto the stage, before he landed back in the audience, dancing with stars like Halle Berry, Denzel Washington and Meryl Streep, before grabbing wife Jessica Biel to lead an audience-wide dance-along.

Watch the performance above.

Justin Timberlake opened the 2017 Academy Awards singing his Oscar-nominated hit single from "Trolls," "Can't Stop the Feeling." After taking the stage with backup dancers for the number, Timberlake headed into the crowd of huge movie stars to get everyone on their feet. Some actors get very into the song. A few looked like audience members at a magic show, hoping they wouldn't get called on.

Jackie Chan
Sporting his most stoic face, Chan put down his pandas to clap along.
ABC
Sting
Sting can't waste his energy getting too into Timberlake's number -- he's got his own performance later in the show.
ABC
Keith Urban
Urban was extremely happy Timberlake came by.
ABC
Nicole Kidman
Like her husband, Keith Urban, she got down to that "Trolls" song.
ABC
Michael Shannon
Maybe Shannon missed rehearsal. It seems like no one told him this would be happening.
ABC
Dev Patel
Patel brought his mom Anita to the Academy Awards with him. Handy that he also got to bring her to a Justin Timberlake concert.
ABC
Denzel Washington
Timberlake took a second while singing to give Washington a high-five. He seemed very excited about it.
ABC
Ryan Gosling
Gosling looks incredulous that Timberlake is ambushing him with a musical number after his work in "La La Land."
ABC
Halle Berry and Meryl Streep
Streep looks to be having a good time, but Berry knows if you get the chance to dance with Timberlake, you take it.
ABC
Jessica Biel
Being Timberlake's wife means you've probably heard this song about 10,000 times, but Biel is still having a good time.
ABC
Javier Bardem
Bardem is having an absolute blast as Timberlake comes by.
ABC
Ruth Negga
Negga was clapping along with the best of them. Compared to Bardem enjoying himself more than anybody in the room, Negga's clapping along almost seems bored.
ABC
Michael J. Fox
Ahead of presenting later in the show, Fox looks like he doesn't want to get too drawn in to Timberlake's catchy song.
