Fox is thisclose to ordering a celebrity spin-off of American Idol, per Variety. The show would likely air this fall and feature 10 well-known singers competing to win $1 million for their favorite charity. The network is hoping to secure the participation of Idol mainstays Ryan, Simon, Randy and Paula, although no deals have been signed. The news comes just days after NBC announced its plan for a D-list singing competition, I'm a Celebrity But I Want to Be a Pop Star. I'm sure that's just a coincidence, though.
