With a 50 year age range from 74-year-old Valerie Harper to 24-year-old High School musical star Corbin Blue! I'm putting my $$$ (that's 2 dollars) on Christina Milian!
Here's the lineup:
Amber Riley - ...who??
Bill Nye - you know "the science guy"
Elizabeth Berkley Lauren
Corbin Blue - yikes he cut his hair!
