Singer Ricky Martin has been chosen to sing the theme song at the upcoming 2014 World Cup in Brazil. Ricky chatted with "Extra" about the song, and revealed the two teams he'd like to see in the World Cup finals. He also dished on his recent collaboration with Jennifer Lopez for "Adrenalina," and the song's "steamy hot" music video. Instead of writing the song himself, Martin teamed with FIFA and Sony to launch a worldwide contest called "Super Song," which asked songwriters to submit their themes. American songwriter Elijah King won the contest with "Vida," which Ricky called "the perfect song."
