Britney Spears may have stopped taking her medication… well at least the pills that allow her to remember dates.

On stage in Washington D.C. last night, Britney wished the crowd a “Merry Christmas!” part way through her performance of Do Somethin’.

On a bright note, at least we know the microphone was live and she wasn’t lip syncing. Here’s the Britney Spears Merry Christmas video. The magic moment is at the 50 second mark.
