Jennifer Lopez Puts In the Work!

Jennifer Lopez is getting ready to bring the heat, again.

The singer just shared some behind-the-scenes footage from rehearsals for the upcoming American Music Awards, where she’ll not only be returning as host but also hitting the stage to perform a medley of her biggest hits.

In the photos, J.Lo can be seen in the studio with her crew of dancers, serving up signature hair flips, powerhouse choreography, and that famous Lopez-level work ethic. Dressed down in a cropped hoodie and leggings, she still manages to look like she’s ready to take the main stage, even mid-sweat!
