She was spotted leaving her local gym in Miami, Florida, alongside fiancé Alex Rodriguez, 44.

J-Lo 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.”

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

Before entering her expensive vehicle, the superstar hugged WWE legend The Big Show.

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

J-Lo plans to enjoy a “casual” holiday after a busy year that saw her star and produce Hustlers, and wrap new rom-com Marry Me with Owen Wilson.

Revealing her Christmas plans, she said: “Christmas Day is very casual for our family.

“We wake up, open presents, have breakfast and enjoy each other’s company.

“Sometimes we wear matching pyjamas to keep things festive.”

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

Alex plans to see daughters Natasha, 15, and Ella, 11, from his previous relationship.
