Britney Spears is sad. Really sad. So we see in "Britney: For the Record," a new MTV doc that trails the beleaguered star as she tries to reboot her life. She starts her mornings with a bowl of Velveeta cheese and grits—"breakfast of champions," her father Jamie calls it— and it's all kind of downhill from there. Lots of crying. Lots of silence. The result is as sunny as Kafka: "I totally lost my way," she says. Sad but true.
