She’s a mother-of-two and recently celebrated her 43rd birthday.

Yet Jennifer Lopez proved she’s still hot property in the performance stakes with a recent live show in Portugal.

The singer put on a free show for 1,500 fans on Thursday as a warm-up to her Dance Again world tour, which officially kicked off in the city on Friday night.

Hot! Jennifer Lopez resumed her Dance Again world tour in Lisbon, Portugal to a huge crowd at the Pavilhao Atlantico on Friday night

The singer lit the city on fire on Thursday in a series of racy costumes after putting on a free show after letting a select group of ticket-holders into her rehearsal.

And on Friday, doors opened at the Pavilhao Atlantico to a 20,000-strong crowd.

Taking the stage in a nude bodysuit emblazoned with red flames, she reigned over the arena with a high-energy performance.

Fans at the show, which was also attended by her four-year-old twins, Max and Emme, cheered wildly when JLo waved a Portuguese scarf.

Both performances saw Jennifer going through her biggest hits and a variety of eye-catching costumes that showed off her toned abs and famous derriere.

After the grueling set, JLo trekked to Germany, where she performed on the country’s hit show Wetten Dass, tantalizing fans in a racy black lace number on Saturday.<

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.
