"You know what? It was perfect because ... he wanted to kind of say, 'You rock,' " Ciara told MTV News at Maxim's Hot 100 party. "And I just kind of felt cool, 'cause Justin can play [piano] real well and he really gets into the music and it was, like, 'Hey, let's make you part of the band.' "
Having Justin in the background for the live performance was very different from the music video for the song, where the two dance quite provocatively with one another. "[We wanted to] do something different and make it fun. It was awesome to see him pick up the keys."
Earlier this month, Ciara told MTV News all about the video's most memorable moment — when she licks Justin Timberlake. "Let me tell you — it's so funny, I have to say this," Ciara said. "I had to lick his ear and do all that fun stuff and bite it. And he had a moment where he was kind of licking on my neck. We were both going back and forth. We were really just freestyling. And Miss Diane [Martel, the director] wanted something edgy, and we all wanted to find a cool way to do it. And that just felt right."
