Could this be a part of a new Britney Spears production?

Earlier this week Britney posted a couple of rehearsal videos for her upcoming Vegas revival of Piece of Me.

Spears began her residency in 2013, and will be there performing until at least 2017.

“Britney performs all her infectious dance songs, as well as tracks from her latest album. But don’t expect a recreation of her music videos. Her intense performances are way more electrifying – some even dreamlike and daring. Whether Britney’s flying across stage, singing in a ring of fire or dancing in front of multiple mirrors, this shining diva knows just how to work it,” according to Planet Hollywood, which hosts Spears’ show.

Spears sings and dances through it all, even wardrobe malfunctions.

She returns to Piece of Me on February 13th.
