The track, which is featured in FIFA's One Love, One Rhythm: The Official 2014 World Cup Album, also appears in the Colombian pop star's new record, Shakira.
The video of 'La La La' features the 37-year-old singer dancing in a black skirt and features special appearances from soccer stars Lionel Messi, Cesc Fabregas, Eric Abidal, Neymar, James Rodrguez, Sergio Agero, Radamel Falcao as well as her longtime boyfriend, Gerard Piqu.
The couple's 16-month-old son Milan also has a cameo in the video and can be seen kicking a soccer ball. Also featured is Brazilian star Carlinhos Brown, who brings the inimitable style that gives the song that all-important Samba feel.
Shakira teamed up with Activia for the video to support the World Food Programme (WFP) and communicate WFP's work to tackle hunger.
Shakira said: "With 'La La La (Brazil 2014)' we want to make a small contribution so that everybody knows about the outstanding work the World Food Programme is doing to fight hunger."
Miami-based rapper Pitbull debuted the official theme for the World Cup, 'We Are One (Ole Ola)', featuring Jennifer Lopez, in April 2014.
