But despite the fame and fortune, at the end of the day she says she's just another single mum.
From the moment JLo hit the stage in a bedazzled body-hugging catsuit for her Perth show last night, it was easy to forget that she's a 43-year-old mother of two.
She's been on the road for the past six months, but the energy and enthusiams in her performance never wavered.More stories from Today Tonight

"Each place is different and new of us, and each one marks a different time in what we're doing," Lopez said.
"Australia is the last place we're going before Puerto Rico, so we're waiting to get to all these places, and we heard it was summertime here, and we were excited about that - because Europe was freezing."
Lopez is a global phenomenon. After selling more than 70 million albums and earning $52 million last year, it's little wonder Forbes named her the world's most powerful celebrity.
"It's quite bizarre because you don't think of those things when you're working and doing your thing. You know, you're just going about your business and trying to do the best you can, and then somebody notices and you're like 'oh that's nice, I like that'," JLo said of the title.
"But that's kind of as far as I go with it. I'm not like 'I am the world's most powerful celebrity' ... I don't think in those terms."
In songs like 'Jenny from the Block' Lopez sings about her humble beginnings, growing up in the The Bronx, but times have certainly changed for the star.
Rumours of diva demands and a refusal to speak to the hired help follow her around the world, but in person JLo is warm and friendly, and happy to talk about family life on tour with four-year-old twins Max and Emme.
"When I took on the whole idea of doing the tour I knew that the babies had to come with me. There was no way that I was going to travel without them for six or seven months, that wasn't going to happen," she said.
"So it was like, 'OK, we have to figure this out', and it's just like any other single working mum. You're like 'OK, who's gonna help me, who's coming, and ho are we gonna do this'."
