Britney Spears is a Vegas girl now. Last year, the "Perfume" singer began a residency at Planet Hollywood and after a successful (though critically mixed) run, she's renewing that contract.

Yesterday (May 12), Spears announced an additional 30-plus shows at the Axis Theater at Planet Hollywood Resort & Casino. Titled "Britney: Piece Of Me," the Las Vegas residency will now run with dates from August 2014 to February 2015.

Spears, who began her string of shows in Las Vegas last December, made the extension announcement on her social media accounts Monday afternoon, including an updated tour schedule on her Instagram.

Check out the picture and the full list of show dates below:

Tickets for the new show dates will go on sale this Friday, May 16.

Spears' "Piece Of Me" residency began shortly after the release of her eighth studio album, the critically mixed Britney Jean, which featured singles "Perfume" and "Work B---h."

Those two singles are included in the show's setlist, though it's largely focused on Spears' hits of the past, including "Baby One More Time," "Toxic" and "I Wanna Go."

Though the production value of "Piece Of Me" has largely been praised, Spears has been criticized for, well, not exactly singing live during the shows, which can cost from $65 to well over $500 per ticket.
