Jennie from the block - may be doing too much.

Sexy singer Jennifer Lopez showed off a very sexy new look - while filming her latest music video. But some of her fans are saying that Jennie may be doing a little bit too much.

Jennifer is 49 years old, and she looks great. But even Jennifer has limits . . . 

The sexy singer showed off her flat abs in a revealing ensemble during a music video shoot with DJ Khaled (not pictured) in Miami Beach. 

The stylish star was surrounded by a large group of well dressed male extras during the shoot. It's nice to see that Jenny from the block is back!

But when the pics (below) leaked, much of the response on social media was NOT been positive.

Lopez just released her new song, “Limitless,” for the soundtrack of her upcoming film, Second Act. She performed the moving anthem at this year’s American Music Awards, opening up to ET’s Keltie Knight about the song before the epic performance.

“I feel so blessed to have Sia write this song for this movie,” she told ET. “Everything that it’s about. I’m excited [for people to] see the performance. It’s, for me, the movie and this song is what the world needs right now. I’m just so proud that I get to do it. Super excited.”

J-Lo's latest sizzling display comes just a few weeks after she posed almost naked for InStyle magazine.

The mum-of-two was proudly showing off her age-defying looks as she posed in a shimmering Valentino haute couture green cape.

She seductively places a hand on her derriere as she flashes her incredible profile to camera.
