I'm checking into Rehab. I need to learn how to cleanse myself from Britney Spears addiction. I can't keep up with this ho! Entertainment Tonight is reporting that she has checked out of Rehab. I think Britney thinks the "One day at a time" thing actually just means "One day" and you are cured. Someone should inform her that it doesn't quite work like that. But before we go jumping the gun here, we need to remember how rehab in Hollywood works. Apparently, you can come and go as you please, so maybe she's just going on a milk and meth run. She'll probably be back in there later on today. We'll keep you posted.
