Up until that time, there were no confirmed reports or diagnoses stating that Britney Spears had Multiple Personality Disorder (MPD), which is now known as Dissociative Identity Disorder (DID).
I would not be aware of them. For the latest and most accurate information, I recommend checking reputable news sources or official statements from Britney Spears or her representatives. Remember that it's crucial to respect individuals' privacy and refrain from making assumptions about their mental health without concrete evidence.
