Justin Bieber and Miley Cyrus to headline TV charity special

Justin Bieber and Miley Cyrus are among the stars who have signed up to perform during an upcoming TV special.

Pitbull, Lady Antebellum, Jason Mraz, Quincy Jones and Glee singer/actor Matthew Morrison will also appear on the Real Change Project: Artists for Education show, which is being staged two weeks before National Teacher Appreciation Week.

In addition to performing, the artists will be shown revisiting their old schools and meeting tutors who inspired them, and they will also sponsor classrooms as part of the initiative.

Liam Murphy, founder and CEO of Real Change Productions, tells The Hollywood Reporter, "Teachers are often the unsung heroes, while actors, musicians and pro athletes get all the praise. I'm willing to bet, though, that each one of us has had at least one teacher who changed our lives forever.

"The goal of our show is to not only honor these teachers but to also inspire Americans to adopt a classroom and support those who are shaping the minds of tomorrow by providing the supplies that enable them to keep making a difference today."

In a post on his Twitter.com page, Morrison writes, "Happy to be part of this TV special to support our teachers."

The program will air on 23 April (13).
