Will Britney Spears rescue Cowell’s “X Factor”?

LOS ANGELES, Sept 11: Britney Spears makes her debut this week as the biggest celebrity judge on US television in a revamped version of “The X Factor” that is looking for its own special something in a stepped-up ratings battle with “The Voice”. In what TV pundits expect to be a tough contest for the most viewers, “The X Factor” returns to Fox television for a second season tomorrow, after “The Voice” moves to the fall slot on NBC for a three-night season opener, starting on Monday.
