In case you haven't heard... Jennifer Lopez's performance of "We Are One (Ole Ola)" with Pitbull and Claudia Leitte at the World Cup in Sao Paulo, Brazil today was a hot, inaudible mess.
No one could hear it!
A source at ITV, which broadcast the ceremony in Britain, said they had “no control” over audio levels because a single feed was distributed around the world.
An ITV spokesman said: "The sound problem that regrettably caused some disruption to viewers was caused by a technical issue with the host broadcaster, which provides the coverage of all the action at this year's World Cup."
Over 62,600 people were in attendance at Thursday's big ceremony, including Brazilian President Dilma Rousseff, UN Secretary General Ban Ki-moon and FIFA president Sepp Blatter.
