Could Cheryl Cole return?
Rate This Image
Music Cred: As 1/5 of the Spice Girls, Scary Spice was part of the best-selling girl group of all time.
Why she would be good: She has a funny, strong personality, yet doesn't come across as too domineering. Plus, she also has "X Factor" experience as a judge on the Australian edition's third season.
Why she could suck: If people had trouble with Cheryl Cole's accent, good luck with Mel B!
Chances: Pretty good. Given that she's already proven herself in Oz, she could work her way from the farm team to the majors. - Melinda Newman
