Four weeks after a standoff with police, Britney Spears is back in the hospital after having been deemed a danger to herself and those around her, Us reports. Spears was taken to UCLA Medical Center late last night and placed on “mental evaluation hold.” Us also reports that the hospital trip was in fact a “carefully orchestrated intervention” and was not the result of a suicide attempt or any other dangerous act on Britney’s part. A source also says that Spears hasn’t slept since Saturday. Because this trip was planned, it is likely that Spears will remain under hospital care longer than her stay from a month ago. This is merely the latest in a series of roadblocks for the singer, whose erratic behavior has already cost her custody of her two sons.
