This was the first time The Black Eyed Peas had worked with Shakira. Will.i.am told Billboard
how he was inspired by the Colombian star's attention to detail. He gave this example of a note she supplied while working on the song:
"When you say that word, can you swing that back a little bit? When I say, 'Girl like me,' the tail end of the reverb, can you make it just a little bit louder?"
"This girl is the definition of music," Will.i.am said. "I've worked with everybody - Whitney Houston, Michael Jackson. I've never experienced that detail. And she conducts the session like she's teaching!"
