So what? Julia Stiles isn't entitled to a moment of human dignity? Stiles can't appear in public anywhere without being treated like a curiosity?
No one has any right to know why she had a moment like this in public, and no one has any right to look at what happened and speculate. Casting aspersions about a personal life is par for the course in the celebrity gossip world. Who cares what it was that bothered her--it's her business and let's leave it at that.
