Britney Spears: This one’s obvious and way too easy, but Brit’s had a spectacularly bad year, so I’ll get it out of the way first. The head-shaving, the booze-and-drugs-gobbling, battling Federline in court and an automobile with an umbrella, the allegedly bad parenting, the rehab stints, the stunningly lackadaisical VMA performance, the laughably awful, “naughty” video for “Gimme More,” and, finally, the indignity of having a number-one album snatched away at the last minute when Billboard decided to change the rules and allow that horrendous new disc by the Eagles, which is only being sold at Wal-Mart, to claim the top spot. Perhaps only Senator Larry Craig and that astronaut lady had worse years.
