Rio de Janiero:  FIFA says Jennifer Lopez will team with rapper Pitbull and Brazilian singer Claudia Leitte to perform the official World Cup song for this year's tournament.

Soccer's governing body made the announcement on Thursday but didn't say when "We Are One (Ole Ola)" will be released.

The song was written and co-produced by Pitbull. Leitte says she is looking forward to "dancing samba with Pitbull and Jennifer Lopez in Brazil."

Lopez wasn't in Rio for the announcement.
