iWon News - Laughs End With Bizarre Britney in Rehab

iWon News - Laughs End With Bizarre Britney in Rehab: "The 25-year-old pop star has been seen wearing skimpy outfits and partying heavily since filing for divorce from Kevin Federline in November, after two years of marriage.

On Friday night, Spears, the mother of two young sons, shaved her head bald. But that didn't send her into hiding as she was later seen wearing an inexpensive blond wig.

'You know, for these celebrities, it's really tough,' New York-based psychiatrist Gail Saltz told The Associated Press. 'They have no idea if anybody likes them for them. ... Everybody wants a piece. Everybody wants to make something off of her, get somewhere by her.'

Spears' very public divorce isn't helping matters, said Saltz, who also suggested that Spears could be suffering from postpartum depression."
