Justin Bieber and Rihanna have been announced as performers for this year's Kids' Choice Awards

Justin Bieber and Rihanna have been announced as performers for this year's Kids' Choice Awards, according to People. The news comes just a week after nominations for Miley Cyrus, the Jonas Brothers and more were revealed.

Nickelodeon is offering an all-access sweepstakes with Bieber to give fans the chance to see the pop star perform at the show. The winner will get a trip for four to Los Angeles, tickets to the show, an invitation to walk the orange carpet, access to Bieber's pre-show rehearsal and a private meet-and-greet with him. Fans will be able to enter the contest at the Kids' Choice Awards Web site March 3-10.

Nickelodeon's 23rd annual Kids' Choice Awards will go live March 27 on Nickelodeon at 8 p.m. ET. and will be hosted by Kevin James. "In short, I guess you could say hosting the Kids' Choice Awards completes me," James said about taking over the gig that went to Dwayne Johnson last year.

Last week, it was announced that the Jonas Brothers, Miley Cyrus, Taylor Swift and "Twilight" were the leading contenders at the show. Fans can start voting for their favorites on Nick.com starting Thursday.

Cyrus, who is up for four awards, will compete with recent awards-show favorites Beyoncé, Lady Gaga and Taylor Swift in the Favorite Female Singer category. Swift is also up for Favorite Song for "You Belong With Me." In the Favorite Male Singer department, Jay-Z fights it out against Sean Kingston, Mario and Ne-Yo.
A rep from Nickelodeon had not returned MTV News' call for confirmation at press time.
