Well who didn't stress out over the judge's telling them something is wrong with them?
Not to mention, of course she's stressed. All of them are stressed. But it appeared that she wasn't 'crying her eyes out' but more 'im worried' stress and -duh- it's a competition so there is going to be a lot of that The only time I've seen her cry on the show was because she was scared they were going to vote her off.
And who wouldn't cry?
