I found this over on hometheaterforum.com, pretty funny:
"Ashlee apparently had her vocals canned even though the band was playing live. So on her 2nd song the band starts playing the 2nd single (according to my wife since I haven't heard it) and Ashlee isn't even singing yet when suddenly we hear her belting out "Pieces of Me" again without moving her lips.
It gets turned down quickly and she sort of goofs around for a second, the band isn't even really playing since they don't know what to do. Finally they kind of kick in to Piece of Me instead but she still has no vocals and is just looking around kinda dancing and squirming over what to do until she finally just walks off the stange and SNL puts up a commercial break card awkwardly.
Then to end the show I guess they figure something must be said so she BLAMED HER BAND for playing the wrong song, I guess hoping we didn't all notice her vocals kicking in for Pieces of Me without her mouth moving."
