Update: June 11, 3 p.m.
Jennifer Lopez appears to have performed a U-turn on her plans to miss the World Cup opening ceremony, and will perform after all.
Eurosport reported a statement from her agents, confirming her presence:
"Jennifer has always wanted to participate in the World Cup opening ceremonies. We have been trying to work out scheduling and logistics.
"Any statements to the contrary were premature. Jennifer would not want to disappoint her fans or fans of futbol. She will be there."
Jennifer Lopez won't be at the 2014 World Cup opening ceremony in Brazil, despite having recorded the official song of the tournament.
Given that she is one of the three key acts in the official song, We Are One, along with rapper Pitbull and Brazilian singer Claudia Leitte, her absence is a surprise.
The other two acts will sing the song before Brazil play Croatia in Sao Paulo on Thursday.
The song has not exactly gone down a storm in Brazil, in any case. The report adds:
The song has disappointed many Brazilians who complain that it sounds too generic for the nation's Bossa Nova-crazed audiences and that it features foreign musicians singing mostly in English and Spanish.
Leitte sings only a few seconds at the end of the song in her native Portuguese.
