‘How is she 50?’: Jennifer Lopez stuns fans in red gym outfit

Jennifer Lopez has showed off her incredible abs in a bright red gym outfit as she headed out for a pre-Christmas workout with her fiance.

Jennifer Lopez showed off her incredible figure in a skin-tight gym outfit as she went for a pre-Christmas workout on Tuesday.

The pop diva, 50, flashed her rock-hard abs and flaunted her stunning curves in the red latex sports bra and leggings.

She was spotted leaving her local gym in Miami, Florida, alongside fiance Alex Rodriguez, 44, The Sun reports.

JLo was then pictured climbing into her Porsche sports car – which was an identical match for her bright red sportswear.

She later shared a photo of her in her bright workout gear with the cheeky caption: “Baby, it’s warm outside. #ChristmasInMiami #ChristmasEveSleigh.”

Fans flooded the comments section of the post, with many claiming she looks decades younger than she is.

“How is she 50?!” one person asked.

“You are flawless inside and out,” another said.

The Hustlers star was contrasted in her bright attire by fiance Alex — who played it casual with a camo hoodie.

Her workout comes after the Jenny From The Block singer and her beau were seen out shopping for last minute Christmas items on Monday.

Lopez will be joined over the holidays with Alex and her 11-year-old twins Max and Emme.
