Meanwhile, rumours are swirling about the status of the singer's relationship with toyboy Casper Smart - her back-up dancer and newly-anointed head choreographer of the tour.

Earlier this week, Jennifer was spotted rocking some serious bling on her ring finger, prompting speculation Casper may have asked the singer to marry him.
Jennifer was in France for Paris Fashion Week with Casper and her daughter Emme when she stepped out with the sparkler.
However, neither party has addressed the claims.

Back in June, Smart opened up to ABC News about what it's like mixing business with pleasure by dating his current boss.
'Sometimes I tell her something, give her notes and sometimes she gives me notes (on performing),' he said. 
'But at the end of the day it doesn’t matter whose position is what because she’s the boss.'

And, he revealed, it was not love at first sight between the pair. To the contrary, a romantic relationship seem to come as a surprise for the both of them.
'It was nothing before, no flirting, no nothing. It's just natural, it just happened,' he said.

Just a few weeks prior to their ABC News interview, rumors spread online that Lopez and Smart had gotten engaged, but JLO quickly put the rumors to rest via her website.
'Rumors!!! Don't be fooled by the rocks that I got,' Lopez wrote, using a reference of her 2002 popular song Jenny from the Block.
'No engagement!'
