What's going on with Britney?

I was watching the news this morning and they were talking about Britney and her latest bizarre behavior. She checked into rehab and checked out only 24 hours later...She shaved her head (That's right she's now bald) and she visited a tattoo parlor and got a number of new tattoos. What's going on with her? I thought she was trying for sole custody of both of her kids? This for sure is NOT the way to do it. I don't think that she deserves to have either one of her kids. Although neither does Kevin. They are made for each other, they just shouldn't be allowed to have kids.
