Aiken and Pickler Lead Celebrity '5th Grader'

You may be smarter than a 5th grader, but how about Clay Aiken or Kellie Pickler or Regis Philbin?

FOX has scheduled a series of celebrity contestants to compete on "Are You Smarter Than a 5th Grader?" during the November sweeps period.

Not surprisingly, the all-stars won't be competing to pocket the potential million dollar prize, with all winnings going to charity.

"American Idol" finalists Aiken and Pickler will lead the celebrity group, along with game show veteran Philbin. Also signed on are skateboarding legend Tony Hawk, Miss America Lauren Nelson and relative-to-the-President Billy Bush.

"Are You Smarter Than a 5th Grader?" will premiere on Thursday, Sept. 6. The Jeff Foxworthy-hosted show will have special Friday airings through early October.
