Britney Spears: In London for "X Factor"

Continuing along on her whirlwind European mini-tour, Britney Spears made her first UK television performance in over four years by appearing on "X Factor" on Saturday night (November 29).

The "Gimme More" singer, who turns 27 on Tuesday, performed her current single "Womanizer," while the show's five finalists each covered a classic Spears tune of their choosing.

The trip to London for "X Factor" followed a performance at the Bambi Awards ceremony in Offenburg, Germany a few days back, along with an appearance on the French TV show "Star Academy" on Friday night.

Now finished up overseas, Miss Spears plans on jetting back to New York City as she readies for a big birthday bash/CD release party on Tuesday (December 2) when her new album "Circus" hits store shelves.
