One A List celeb in particular RSVP'd at the very last minute with a huge list of demands. One thing known about Saturday Night Live is they don't bend over backwards to cater to anyone. The celeb's demands were denied and the celeb had their people tell SNL that they wouldn't show. This was fine with them, as you can tell from the show...they had more than enough star power. This person showed up anyway and was placed next to someone they can't stand. The photos captured their displeasure, but even more hilarity is that they put them together on purpose since #1 on the list of demands was a list of people they didn't want to be near. This person was #2 on the list...the first one wasn't there. They actually relocated a person who was sitting there just to place the high-maintenance celeb there.
The event managers had some great laughs when the person the celeb didn't want to sit next to then tried to hang around them the entire after-party. The celeb couldn't say anything, if they did, their image would take a hit.
