We all know we were starting to miss Britney Spears. She went home on Wednesday night and didn't emerge until yesterday evening when she went to the Millennium to dance, dance, dance.
This just goes to show you that if she want's privacy she can very well get it. No one knew she had left the house. The paparazzi was just probably tipped off that she was at the dance studio.
On a side note, some stylist came forward this week claiming to have gone to Britney's house and worked on her hair. Her hair definitely didn't look like it had any work done. It actually looked worse than before. That stylist should never work again if he prides himself in that.
