As part of the promotion for her new album Circus, Britney Spears will be heading to London to give a live performance on the TV show X Factor.
She is expected to sing her hit Womanizer.
The appearance will also help generate interest for 2 concerts she'll be giving in London next June. Those will be the only European gigs on he world tour.
X Factor is a show where successful singers give tips to contestants. Brit will only be performing, not coaching.
