Complete Rundown of Celebrity Cameos in Justin Timberlake's 'Can't Stop the Feeling'

— -- Is Justin Timberlake's new song the song of the summer? Based on the sheer amount of celeb cameos in the music video, it certainly seems so.

It's only been just over 12 hours since Timberlake dropped his new song "Can't Stop the Feeling," but the Internet can't get enough of it. The song will be featured on the soundtrack for "Trolls," the animated film in which Timberlake also stars. It hits theaters September 23.

The upbeat track is perfect for the summer time as JT croons: "I got that sunshine in my pocket/Got that good soul in my feet/I feel that hot blood in my body when it drops/Ooh!"

The song came complete with a music video in which Timberlake, 35, is seen gathered around friends and family in a recording studio as he plays them the track.

While one cute cameo is particularly memorable -- JT's mother, Lynn Bomar Harless -- there are plenty of other celebrity cameos throughout.

Here's a complete rundown of who we spotted dancing and singing along in Timberlake's "Can't Stop the Feeling":

Gwen Stefani
The No Doubt singer is seen grooving to Timberlake's track in her truck. Wearing a purple and red sparkly top with her signature red lip, Gwen attempts a few dance moves while she drives.

Anna Kendrick
The "Pitch Perfect" actress, who is also starring in "Trolls," dances and lip-syncs the JT track in her dressing room. Along with busting some moves, Kendrick, 30, sings the sunny song into a hair brush.

James Corden
The late-night talk show host, who is known for singing alongside pop stars in his viral "Carpool Karaoke" series, dances to Timberlake's song on the beach. He sports a blue bomber jacket and sunglasses. Perhaps he stayed up all night.

Kunal Nayyar
"The Big Bang Theory" actor throws what appears to be a script into the air before he breaks out into a dance in the music video. And Nayyar, 35, really goes all out, dancing on a couch and even hopping onto a wooden table.

Icona Pop
The Swedish duo are seen in what appears to be a backyard barbecue, surrounded by puppies, in JT's music video. Icona Pop's Aino Jawo and Caroline Hjelt lip-sync the song while holding the adorable dogs, including one chocolate miniature dachshund.

Ronald Funches
It's hard to miss the stand-up comedian, and another star of "Trolls," in Timberlake's music video. He gets the coolest background for his scenes, dancing in an old-school arcade.
