The pop starlet, 29, took to the Palms Casino Resort's Rain Nightclub stage in Las Vegas recently, previewing three new songs from her upcoming Femme Fatale album.
During a 45-minute set that included three short breaks for costume and stage changes, Spears performed Hold It Against Me, Big Fat Bass and Till The World Ends.
In her first public performance since her successful Circus tour in 2009, Spears appeared on stage in front of a prop electric chair while singing Hold It Against Me.
With her boyfriend, Jason Trawick, and father, Jamie Spears, looking on from a VIP area, she later appeared inside an oversized boombox during the Big Fat Bass number, dressed in a tight black outfit and policeman's cap.
To wrap up the show, Spears sang Till The World Ends dressed in a one-piece brassiere with her breasts highlighted by blinking red lights.
