Well, I used to write O-Z-Z-Y on my fingers

So Britney left rehab for a bit to go to an AA meeting (I don't get it either) and people noticed that she had writing all over her hands:

' The 'Toxic' star, who hid her recently-sheared head under a brown wig and hat when she left Malibu's Promises treatment centre to attend an Alcoholics ' Anonymous meeting, shocked onlookers by revealing the strange doodles all over the backs of her hands. Flowers and the word 'Push' could be made out among the scribbles. A smiling Britney met with photographers and an eyewitness described the troubled mother-of-two as 'relaxed and in good spirits'. '


Hmmm, flowers and "PUSH" Maybe it is postpartum.

Also, I can't believe they let her have pens in there!
