Then, it cuts to her holding her hair up and singing the first lines in front of a white background. There are also black and white scenes of her wearing a white leotard behind a foggy glass. She then appears wearing the leotard and glasses, while surrounded by four female dancers wearing black outfits, hanging from a raised barre. The word "sin" is censored and changed for the word "this" during the pre-chorus. In the chorus, she dances in front of a white wall with barcode-like light installations with six male dancers. There also scenes of her dancing provocatively with two male dancers. At the bridge, there are intercut close-ups of her that end with a smirk. The video concludes with Spears dancing with the two male dancers and cuts to a close-up of her looking into the camera. "Rolling Stone" writer Daniel Kreps compared the video with the music video of "Single Ladies" and complimented the choreography saying Spears had not danced with so much conviction since the "In the Zone" era. Bradley Stern of MuuMuse likened the video's choreography and dancer's wardrobe to Janet Jackson's "Feedback" video. Jocelyn Vena of MTV gave the video a positive review, stating that it's a "sexy, fast-paced clip" and that "there are a few moments in the video where Britney's personality shines" adding that "she smiles at the song's tongue-in-cheek lyrics, particularly when she finishes the song's bridge." Tanner Stransky of "Entertainment Weekly" complimented the video's choice of wardrobe, but said that the video was "sparse", adding "there's not much to the single besides trite, ridiculous advocation for a ménage à trois anyway, so why would the video go any deeper?". On December 15, 2009, a director's cut version of the video for "3" leaked online. Kreps commented that the new version "offers up a slightly more NSFW edit of Martel's dance-heavy vid that seems to find a better cadence with the music, as opposed to the original version, which was essentially filmed and edited in the matter of days to coincide with "The Singles Collection" release". On March 25, 2011, Spears performed a special show at Rain Nightclub in Las Vegas. The setlist of the show consisted on three songs from her seventh studio album, "Femme Fatale", including "Hold It Against Me", "Big Fat Bass" and "Till the World Ends".
