You gotta love Demi Moore and her endless Twittering. How else would one find out why she wasn't at the Golden Globes? As she explained via Twitter, she was "feeling sick and having a bad hair day." A day later, she nursed herself back to health, proclaiming, "Feeling better and the sun is out but my hair is still askew!" (It looks pretty good to me, Dem.) My hair always seems to play up on important days when I simply must leave the house, but you know what they say: the show must go on (in a slicked-back-hair-up kinda way). How about you, has bad hair ever threatened to keep you away from something?
