"I forgot that ever happened," Witherspoon said at the time. "He did say that, and no, it wasn’t scripted. He didn’t tell me he was going to say that before it happened on air. So, I was a little bit flummoxed in the moment." 

Witherspoon added that while "gender norms have changed quite a bit" in the last two decades, the few women in Hollywood who make "a lot of money" are still "shamed" for it.
