Jennifer Lopez stumbles and nearly falls flat on her face during dance number at new Vegas show

Jennifer Lopez nearly ended up on the floor while performing her 2011 song On The Floor in Las Vegas this week.

The 56-year-old entertainer – who has been 'pushing herself to exhaustion' – was singing and dancing to the tune when she stumbled and almost fell on stage at The Colosseum. 

But the seasoned performer quickly rebounded from the mishap, laughing it off and picking up the choreography without missing a beat.

The moment was captured and shared by JPASC24 via Instagram on Saturday.

He wrote in the app's Stories feature, 'No one recovers from a trip quite like @jlo.' 

The Bronx-bred star was dressed in a sparkly black and white tuxedo costume, baring her toned legs in nude-toned fishnets during the high-energy number.  

Lopez is in the thick of her latest string of shows, which kicked off on March 6 and runs through March 28 at Caesars Palace.

Earlier this month the Daily Mail learned that the lifelong artist had been working nonstop to prepare for the Sin City production.

'Jennifer is rehearsing night and day to make sure the show is spectacular, better than ever,' a source shared.

'She is working 13-hour days at a studio in North Hollywood with her back-up dancers to make certain she looks like she is on top of her game. She always says she wants to be "better than yesterday" – it's her thing.' 

Another reason she is putting so much energy into the shows is that she wants her act to be considered one of the top draws in Las Vegas.

'Everyone is going to the Sphere these days, that is the town's big deal, so she wants to prove that a more old-fashioned concert at the Colosseum is still the place to be,' added the insider.

She also wants to remind fans that even though she is well into her fifties, she is still in her prime.

'Jennifer loves to work, she never complains, it's her jam,' said the source. 'Some people like to vacation on the beach in Hawaii, and some like to work nonstop. Jennifer is the latter. She feels proud to be doing so well at her age and as a Latina woman.'

The shows will also feature some guests along the way. 'There will be a lot of excitement and surprise stars,' teased the person close to the singer. 

It comes after Lopez previously brought out Ja Rule, with whom she's collaborated on songs like I'm Real and Ain't It Funny.

Lopez called the concert 'the quintessential JLo Show' while speaking with Extra.

She explained, 'You see who I am, I think, as not just an entertainer, a performer, but as an artist and as a human.

'I still do all my hits and all the songs that people know me for, but it's really done in a very fresh and exciting way.'

And she explained why she's working so hard, adding, 'I'm in my happy era and I have that in the show… I've never looked at it as a job. It's just what I love to do.'

It comes more than one year after Lopez's divorce from Ben Affleck, her fourth husband, was finalized.
