OMG! I cannot believe Hayden chopped off her beautiful locks! Why? Oh, why? Is she doing this to look tougher for her new boyfriends? Seriously, I’m shocked! Hayden also got a darker hair color. She is such a beautiful young lady but this new hairdo makes her looks a lot older. What do you think: hot or not?
