Letterman Stumps Paula Abdui Over Difference Between ‘X Factor’ And ‘Idol’

Paula Abdul was recently featured on David Letterman’s Late Show to promote her new reality TV singing competition “The X Factor.” Taking advantage of the opportunity, Letterman decided to grilled Abdul about the differences between “X Factor” and “American Idol.” Naturally, she was befuddled over the differences like a deer caught in headlights.

I guess to her credit, Abdui has never looked better for her age.

“The X Factor” premieres Wednesday night on FOX.
