Britney Spears is set to perform on New Year's Eve and on Valentine's Day during her Las Vegas residency.

The star's "Britney: Piece Of Me" shows will kick off on December 27 and continue for two years at the Planet Hollywood Resort & Casino, and she's set to perform four of those shows before the end of 2013.

16 dates have been announced so far, beginning on January 29, following a brief hiatus after her New Year's run of shows. So far she's set to perform on alternating Tuesdays and Wednesdays, and also on Fridays and Saturdays.

Britney's new as-yet-untitled album, her eighth studio recording, will be released on December 3.
