I understand feeling disappointed, but to say that shit out loud makes you look bad and is disrespectful to your co-headliner(s). She acts like she's the only one that ever had to share the stage at the Superbowl. Many halftime shows have featured more than one artist. Janet and Britney both shared the Superbowl stage with more than one other act and, at the time of their performances, I would argue were a much bigger draw/name than Jennifer Lopez.
