Perhaps next time Jessica might consider lip syncing like Ashlee because it seems she can't quite remember song lyrics. Jessica Simpson forgot the lyrics to Dolly Parton's Song "Nine to Five" while performing with carrie Underwood. Jessica apparently left the stage and was in tears. I've always thought the lyrics to Nine to Five were pretty easy to remember. When someone with breasts as large as Dolly Parton's sings, you general pause and take note. At least until you finish undressing them with your eyes. But I can see why Jessica Simpson might have forget the lyrics, after all the word "Working" does go right before the Nine to Five part. Oh and in case you're wondering, I doubt this picture of Jessica Simpson is from the Kennedy Center perfomance, but if it is - way to go.
