Jessica Simpson had a bad night onstage while opening for Rascal Flatts in Grand Rapids, Michigan yesterday. The singer forgot her lyrics, struggled with her ear monitors, mumbled through songs, teared up and asked her band to re-start a song.

She eventually said "I'm Sorry" to the crowd. I don't think this was at bad as her sister's lipsynching SNL fiasco!  If you dont remember here is a clip below:
