They may be united in song, but ask these four singers who they want to win the World Cup and they start to disagree.
Puerto Rican star Ricky Martin said: "Unfortunately, Puerto Rico is not in the World Cup. Brazil or Argentina?"
Netherlands, said Indonesia's Judika.
Alif Satar, from Malaysia, said: "Every time I say I want England to win, they don't. So this year I'll say I don't want them to win."
Singapore's Sezairi Sezali is rooting for Korea because it would be "cool to have an Asian team".
"But Spain really has the best players in the world right now," he added.
It's heartening to hear these lads know their football teams, considering they've lent their voices to Vida, one of the tracks on the official World Cup album, One Love, One Rhythm.
It is due to be released on May 12.
Vida is the winning entry of the 2014 Fifa World Cup SuperSong contest, organised by Sony Music last December.
The contest gave fans an opportunity to write a song for the official World Cup album.
The winning entry was written by US singer-producer Elijah King, and was selected by 42-year-old Martin from more than 2,000 contest entries.
Singapore Idol 3 winner Sezairi, 26, joins Malaysian singer-actor-host Alif, 23, and Indonesian Idol 2 runner-up Judika, 35, for the Asian version of the song.
The song was unveiled last week to regional media at a Jakarta press conference.
They sing along in Malay and Bahasa Indonesia to Martin's Spanglish, though the singers recorded their parts separately.
Martin joined the press conference from Sydney via Skype because he is recording the third season of reality TV singing series The Voice Australia, where he is a coach.
He said: "A few months ago, I received a call from Sony Music saying, 'Hey, Fifa wants to work with you once again'.
"When you get this kind of phone call, you either get really excited or you get really excited."
Martin is no stranger to singing for the World Cup, having sung La Copa de la Vida, or The Cup of Life, for the 1998 World Cup in France.
That song topped charts in several countries, including Australia, France and Germany.
