See? We told you she was mature for her age! Of course, better proof of her maturity came a few minutes later when she returned to her car to find a parking ticket waiting on her windshield. We don't know about you, but we probably wouldn't have handled the conversation with the parking attendant any better than Hayden - way to not throw a tantrum or play the "But I'm a cute blonde celeb!" card, Hayden!
