Spears Drops K-Fed, Neckline
Britney Spears showed up to Sony Music Studios late last night with her security detail and her, um, two closest friends in tow. 
She pulled up in a stretch limo and waited inside the car until security was prepared to open the doors to let her in the building. One member of security can be seen on the phone calling for someone to let them in, warning the paparazzi, "No one stops our feet, OK?!"
Britney emerged from the car wearing an extremely revealing collared shirt, and rushed passed photogs as they yelled, "Britney, you look gorgeous." We concur.
Photogs spotted Britney earlier in the week wearing a gazonga-revealing outfit. Splitting with K-Fed has done wonders for the girl(s).
