Additional celebrity contestants will be named soon along with the hosts of the show, the network said.
"'I'm a Celebrity…Get Me Out of Here!' is the ultimate 'Swiss Family Robinson' as 10 celebrities will be dropped into the heart of the jungle to face fun and comedic challenges designed to test their survival skills," NBC said in a news release.
"America is the puppet master, controlling their favorite celebrities by putting them into challenges and tasks to win food, supplies and luxury items. In each episode, friendships will be tested, hilarity will ensue and viewers will decide which celebrities stay or go. The last remaining star will be crowned King or Queen of the Jungle, winning a substantial cash prize for their favorite charity."
Ousted Illinois Gov. Rod Blagojevich, under federal indictment for allegedly trying to sell state appointments for campaign contributions and other benefits, had been scheduled to participate on the show, but a federal judge this week denied him permission to travel to Costa Rica.
