After screwing up the lines to Dolly Parton's hit "9 to 5," during filming of a tribute to Dolly Parton for the "Kennedy Center Honors," Jessica simpson begged for a second chance to sing the song. Well, she got it and what does she do? She wastes our time again!

Unhappy with her second taping of the song, she pulled out of the show, which will air Dec. 26 on CBS.

"She really wasn't happy with her performance and she did want it to be perfect for Dolly, who she idolizes," said Cindi Berger, a spokeswoman for Simpson.

"We appreciate the time and energy Ms. Simpson put into this event and respect the high standards she has for herself and that of the Kennedy Center Honors," George Stevens Jr., show producer told the press.
