Nobody was actually applauding or cheering at the Screen Actors Guild Awards last night.

We know that now, because in the middle of Reese Witherspoon's presentation of the award for Best Actor in a Supporting Film Role, some intern in the booth hit the red "Applause" button, and ruined the gleaming facade of Hollywood forever.

In the clip above, Reese laughs off the error, saying "What was that noise? It wasn't me."

But you can tell she's panicked that people finally know celebrities' hands are so frail they can't even applaud one another. Those aren't her fingers prying open the envelope; it's all CGI.
