In maybe the most powerful work of journalism ever, Us magazine asks the the daring question: "Is Britney Spears Bipolar?" They consulted a psychologist who's never actually seen Britney and let her go wild with speculation:

"Her erratic behavior has moved into bipolar disorder. Your energy level and emotions alternate between highs and lows, and that seems to have happened here. It seems that Britney has a mood disorder. She strikes me as someone going through a delayed adolescence."

Powerful powerful stuff. Especially coming from somebody's who's never actually treated Britney. Hey, you know who else hasn't treated Britney? Me. So here's my professional opinion: she's fucking nuts. >
