Britney Spears went out in costume to the Halloween Party held at The Green Door in Hollywood. The confused singer, dressed as a local paparazzi agency, TMZ, goes into the club in a full pink zebra regalia with sombrero hat and eye mask! Not too sure what the connection with the outfit and the theme is but forgetting her camera, the key prop of the outfit, Britney comes running out of the club, in sweat pants, pink hoodie and Lolita love heart glasses! This time wearing her TMZ press pass! The scantily clad, Britney makes sure her sweats are low enough so her tattoos are showing. The singer heads back into the club ready for camera action. Staying until the last is tune played, Britney leaves wearing a peak hat with her sombrero on top. The mad hatter is back!
