You're talking about this interview, correct?
IMO, she's being very calculated in her statement here. I think she had planned out exactly what she wanted to say to the media and how she wanted to say it. It may not have come across as well as she intended, but I don't believe she was truly ambushed in that initial interview. (I may be imagining this, but I think I see a little half-smile, i.e. duper's delight, right before she walks away from the camera.)
Now in her subsequent interactions with the media, I think she did truly feel overwhelmed and ambushed, that's why she started snapping at reporters.
