Jennifer Lopez kicked off the FIFA World Cup 2014 in style on Thursday, as she performed at the Opening Ceremony in Brazil.

The 44-year-old singer showed off her incredible figure in a sparkling leotard she sang the official FIFA song We Are One (Ole Ola) alongside rapper Pitbull and singer Claudia Leitte.

There had been initial reports that Jennifer was due to drop out, but by the looks of her energetic performance there was nothing that could have kept her away from the stage.

It has certainly been an emotional time for Jennifer, who after splitting from her boyfriend Casper Smart, was rumoured not to be making an appearance today.

There had been reports that Jennifer was bouncing back to happiness with dancer Maksim Chmerkovskiy – but J-Lo has since denied the report, tweeting: ‘No I’m not. #rumors #nottrue’ responding to a question about the romance from a fan.

People reported that J-Lo met the 34-year-old hunk through mutual friend Leah Remini and claimed the two having been taking their time getting to know each other, as they are both busy with their careers.

Maksim was previously linked to Kate Upton, who at 22 is exactly half the age of J-Lo.

Meanwhile, appearing to confirm the rumours, Jennifer and Leah attended Maksim’s brother Val’s birthday party in Los Angeles in March.

And the insider believes they may become an official couple, saying: ‘I think they could. Who knows what will happen?’

But multiple sources with Us Weekly deny the romance, saying that the two are ‘just friends’.
