On Saturday, the mom-of-two was filmed by pal Loren Ridinger dancing to Latin music at a nightclub in Miami.
The Shades of Blue star paired her form-fitting top with a set of white, dressy trousers.
Jennifer showed off glowing skin with a smokey eye, bronzed cheek and a light-coloured lip. She accessorized with stud earrings, rings and multiple bracelets.
The former American Idol judge took a bathroom selfie with her entrepreneur pal, Loren.
In the snap, Jennifer poses with her back towards the mirror, while her friend makes a duck lips face.
'Miami nights @jlo #bathroomselfie #loveher #casatua,' she wrote.
