 The song was a major part in The Circus Starring Britney Spears ( 2009 ) , as the encore of the show . After a video interlude of Spears 's music videos set to " Break the Ice " ended , Spears appeared wearing a police officer uniform designed by Dean and Dan Caten , with black sunglasses , a hat with her trademark logo and sequined handcuffs . Her female dancers were also dressed as policewomen , while her male dancers were dressed as criminals . During the performance , she danced and flirted with the male dancers . At the end of the song , she returned to the main stage while her dancers surrounded her and a shower of sparks fell over them . She thanked the audience and bowed to each side of the arena . She left the stage with an instrumental version of " Circus " playing in the background . Jane Stevenson of the Toronto Sun praised the performance for being a standout number in the show .
