Jennifer Lopez is performing at the World Cup after all.

JLo says she is flying to Brazil to sing at the tournament's opening ceremony in Sao Paulo on Friday morning (WA time), before the host country takes on Croatia in the first game of the tournament.

FIFA officials announced earlier this week that the singer wouldn't perform the official tune We Are One alongside Pitbull and Claudia Leitte but Lopez said on Tuesday that the announcement was premature.

She said: "We always were going," to the World Cup but her crazed schedule had made things difficult.

The 44-year-old is also busy promoting her 10th album, A.K.A., to be released next week and is dealing with a split from boyfriend of two years Casper Smart, who has been accused of cheating on her with transsexual models.
