Britney Spears, Ladies of ‘Grease: Live’ + More to Appear at People’s Choice Awards

The 2016 People's Choice Awards' roster is shaping up to be quite a crowd-pleaser.

Today (December 21), CBS announced that Britney Spears, Gina Rodriguez, Meghan Trainor and many, many more will be on hand for the show, which airs January 6, 2016 on CBS and honors the best in TV, film and music. John Stamos, Maddie Ziegler, Priyanka Chopra and the ladies of Grease: Live (Carly Rae Jepsen, Julianne Hough, Keke Palmer, Kether Donohue and Vanessa Hudgens) will also attend.

Between winners' announcements, which are determined entirely by public vote, Shawn Mendes and Jason Derulo will perform. Executive Producer Mark Burnett said in a statement that viewers should be ready for magic.

"Jason is such an all around incredible performer and triple threat in the industry,” he said. “We are thrilled he is coming to perform and he will bring the perfect energy to our show.

Most categories — which span from Favorite Action Movie Actor to Favorite Streaming Series — have closed, but the public can still vote for Favorite New TV Comedy and Favorite New TV Drama until the night of the show. Jane Lynch will host.
