The actor/comedian/TV host was announced Tuesday as the chairman for Nickelodeon's soon-to-be re-branded channel for teens -- formerly The N, and now TeenNick -- and celebrities like Taylor Swift, Ellen DeGeneres, Sharon Osbourne and, yes, Mariah Carey, all appear in a new promo to congratulate him on his new gig.
"I started my career here at Nickelodeon and am so excited to be back, serving as an integral part of TeenNick as the in-house voice and representative for teens everywhere," Cannon says in a statement. "TeenNick is their network and I am here to make sure this is an ultimate destination for and about them."
The N officially becomes TeenNick on Sept. 28.
It's a two-year deal for Cannon, 28, who will not only be in front of the camera, but making behind-the-scene decisions for the channel, which launched him to stardom with All That and The Nick Cannon Show. His first order of business will be to produce and host the TeenNick HALO Awards, an hour-long special that will feature Cannon and his famous friends as they surprise teens and recognize them for their good deeds. The special is scheduled to premiere in December. --Michael Y. Park
