Nickelodeon has set a Feb. 21 premiere date for the Nick Cannon-directed movie, “School Gyrls.”

The movie, also written by Cannon (“America’s Got Talent“), will feature teen popsters the School Gyrls, discovered by Cannon, and guest appearances from Justin Bieber, Soulja Boy, Angie Stone, Pete Wentz and others.

It will premiere on Nickelodeon, then air on TeenNick the following night.

“For me, the movie has an appeal like ‘Glee,’ ” Cannon told The Post. “It has that poppy look but it’s a way to do a young teen musical that’s a little hipper than the ones you may have seen.”

In the movie, the School Gyrls (Mandy Rain, Jacque Nimble, Mo Money) play students at an exclusive all-girls academy who meet each other in detention, bond, and hatch a plan that unfolds at the school dance.
