What happened at the end of Taylor Swift's CMA performance...?

I was reading on another board where someone claimed to have been in the audience and that a steaker tried to run up on the stage. If you watch the video when she looks surprised and says "what", you can see just the heads of the audience, but can clearly see that all heads turn and look in the same direction that she did. There appears to have been something going on in the audience from the reaction of the other people. It definately wasn't a reaction to the standing ovation or lack there of, because she was definately surprised and confused, and she's too classy to act like that for not receiving one. Miranda Lambert is thought to have referenced it (a streaker) with her following statement saying "now we all need to go to church" or something like that. I think that makes the most sense and would definately explain the shocked look on her face, as well as explain the curtain lowering so quickly when it didn't do that for any other performer.
