Songfacts®:

• This song features Ciara's Jive Records label mate Justin Timberlake, who also co-wrote and co-produced the track. Rather than recording their vocals separately, the two stars recorded the track together in a studio. Ciara told Ed Lover of Power 105.1 that beyond Timberlake's musical gifts, she was also impressed by his personality. She explained: "He's a comedian. I think that all of us can agree – at least if you've been watching some of his stuff lately – that he's really becoming more and more silly… His personality is amazing."
• The song was originally created by Justin Timberlake as a demo track called "Magic."
• The song's music video was directed by Diane Martel, who previously helmed Ciara's promos for "Like A Boy" and "Promise." Ciara said of the promo to MTV News: "It's all about showing another side of me with this video. I'm basically giving you a show you'd see in Vegas - and it's my love, sex and magic show. He's the voyeur and I play with him a little bit. I got my inspiration from the Crazy Horse [Cabaret] show and just from the shows [in Vegas], period. It's giving you the elements of love and sex and magic."
• Timberlake told MTV News: "I just kind of wanted to create a song for a female that was along the same lines as a male who could have swagga on an album. She just fit the song so perfectly."
• This was the first song by a female artist to reach the Top 10 of the Hot 100, which contained the word "sex" in the title. Prior to this song, 12 other sex-titled numbers had reached the Top 10, all by male artists or groups. One of them was another Justin Timberlake song, "SexyBack."
• Ciara explained to Digital Spy how her collaboration with Timberlake came about: "Well, Justin had some records that he wanted to play for me and I happened to want to work with him. We've got the same manager so everything came together easy. It's funny because we met each other years ago but never really hung out or anything. But now he's kinda my new music buddy and I'll come to him with an idea and say, 'Hey, listen to this, what do you think?'"
