"Beyonce was supposed to be at the Emmy's" - Jimmy Kimmel
While talking to Jimmy Kimmel, John Oliver said he was disappointed that Beyonce was not at the Emmy's and Jimmy Kimmel replied saying that Bey was supposed to be at the Emmy's and that there were even assigned seats with her name. He also said that he was thinking of what to say to Beyonce while he was presenting because with Beyonce at an award show you have to acknowledge the queen. from 5:35-6:00
It's sad that she wasn't there, but maybe it was better this way.
It would've been pointless to get ready for hours to make it to the show and then to loose the award.
