Other judges for the Saturday pageant in Las Vegas are Miss America 2002 Katie Harman and musician Dave Koz.
Organizers say the judges were picked because they are distinguished in various fields, including entertainment, business and the arts.
The pageant hosted by Extra host Mario Lopez will crown its 2010 winner on Saturday night at the Planet Hollywood Resort and Casino. Lopez is hosting for the third time.
The show will air live on cable network TLC.
