Justin Bieber and Rihanna will both take the stage during one of the year's sexiest TV events -- the Victoria's Secret Fashion Show!
ET was first to exclusively announce Bieber's performance on the highly-rated show, set to air Tuesday Dec. 4, at 10 p.m. ET/PT on CBS. It was later revealed that in addition to the teen heartthrob, R&B superstar/actress Rihanna and singer-songwriter Bruno Mars will also perform during the broadcast.
Of course the show will also feature the world-famous Victoria's Secret Angels -- including Miranda Kerr, Alessandra Ambrosio, Adriana Lima, Doutzen Kroes, Candice Swanepoel, Erin Heatherton, Lily Aldridge, Lindsay Ellingson, and many more.
Bieber -- who remains one of pop music's most successful young stars -- became the first solo artist in history to send four songs from a debut album (My World) into the Billboard Hot 100's Top 40 prior to the album's release. Three years later, his latest album Believe also has four songs in the Top 40 on the Billboard Hot 100.
