She's been preparing for months and on Friday night (December 27), Britney Spears finally debuted her Vegas show "Britney: Piece of Me."

Powering through dozens of hits in 90 minutes, the "Toxic" singer danced in a ring of fire, flew around stage in an angel costume, and danced the night away.

Starting the show with "Work B**ch," the event was sprinkled with new songs, but gave fans plenty of her crowd-pleasing hits.

Plenty of famous faces stepped out to support her as well, including Miley Cyrus, Katy Perry, Adam Lambert, DJ Pauly D, and Mario Lopez, who she brought on stage for "Freak Show."
