Britney Spears has reportedly been banned from the 50th Anniversary of the Grammy Awards. Recent sightings of the troubled star at Hollywood’s Millennium Dance Studio, where she is said to be rehearsing for her new music video, had sparked speculation that the fallen pop star may have been a performance for the February 10th ceremony. No dice says, the New York Daily News. “Britney is banned from the building,” an NYDN spywitness reports.
