According to AJessFriend, a moderator at Jessica Simpson’s official message board and personal friends of the Simpsons, Jessica will not be appearing on anymore episodes of ‘That ’70s Show’ as previously scheduled. This is what he had to say:
I found out today that the other two episodes that were scheduled to include Jessica were to be shot next month, close to wedding time. Therefore, Jessica will not be making any more appearances on the show.
