The fallout over Boobygate continues: Janet Jackson will apparently not appear at Sunday's Grammy Awards, where she was slated to introduce a tribute to ailing R&B singer Luther Vandross. According to reports, CBS rescinded her invitation in the wake of her Super Bowl striptease. The network declined to comment. Meanwhile, NBC has removed a scene from tonight's ER that would have shown a female patient's bare breast because "the atmosphere created by this week's events has made it too difficult for many of our affiliates to air this shot." Finally, the NFL has yanked 'N Syncer JC Chasez's halftime performance from this weekend's Pro Bowl game and replaced it with some Hawaiian dancers.
