In the clip -- also featuring Pitbull -- Lopez, clad in black lingerie, packs on the PDA with Smart, 24, and gets hot and heavy with her other backup dancers in an orgy scene similar to the image being used for the single's artwork.
"It was just a very natural thing for us to do together," she told Extra of teaming up with Smart. "Everything that the song is saying -- where I'm at -- it was just very natural. It didn't feel forced."
Agreed Smart, who dons a blindfold with the phrase "Love Is Blind" in one scene: "Me and Jen work well together. On set we work so well together and they were long shoots 16, 17 18 hours. Maybe it was the chemistry or whatever it was, but it didn't seem like it was that many hours. We worked really well together, it was great."
