Jennifer Lopez and Pitbull will join Brazilian singer Claudia Leitte on the official World Cup anthem. It's called "We Are One."

Pitbull said: "We are here to break down barriers and show that through sports and music we are one."

Leitte said the song would show off her country's love affair with musical and sporting rhythm.

She said: "Music is my passion and football is the passion of the Brazilian people. We want to show the passion and the culture, that's what we have in this record. We are in the finishing phases."

Jennifer Lopez wasn't at the event to introduce the song so she didn't have a comment.

The track will be released soon.
