The Voice judge told Glamour magazine of the song, "Working with [Rihanna] was utopia. She's the sexiest woman on the planet. And at the end of the day, we're both just basically Caribbean girls. The chemistry was so good and so real. She taught me dance moves. She was a sweet teacher."
In addition to the new track, Shakira, 36, also tweeted a behind-the-scenes look at her mixing the song.
