Has any show in TV history ditched Nicole Scherzinger and not improved drastically? How about Paula Abdul? Okay, so Idol has never really filled that Paula-shaped hole, but the reshuffled judge panel on X Factor can only mean better days after an underwhelming debut season. Demi Lovato, yeah yeah, but the real reason to watch: Britney. The very idea of our girl on live TV, speaking words no less, is enough to push the "gimme more" button. Bold prediction: This will make an even finer Brit TV series than Britney & Kevin: Chaotic.
