Oh, Jessica...get it together...

While performing a tribute to Dolly Parton at the Kennedy Center Honors, Jessica Simpson apparently had a meltdown. In the middle of her rendition of Nine to Five, she fumbled the words and ran off stage muttering "so nervous." Apparently the audience was too stunned to react and just sat there completely silent. When she and other singers in the tribute came back on stage Jess was crying. The show airs on CBS December 26 at 9 p.m. I wonder if they'll keep that part in?
