Britney

First Britney's traipsing around with that model of good taste, Paris, showing her panty-less crotch to the papparazzi and hence, the world. Then she's checking into rehab after something like 37 days of straight clubbing while da babies languish with various nannies and mannies. Then she's checking out of rehab after only a day and as a followup, has a meltdown and shaves her head, only to don a horrifying wig. Then she's back in rehab, and then out again...

Seriously, Britney's in need of some serious intervention...
