Singer-actress Jennifer Lopez doesnt need a cape to look and feel like a superhero. The El Anillo singer, 49, showed off her buff biceps in a clingy maroon dress and silver hoop earrings on Instagram. With her hair swept back, Lopez flexed her incredible arms as she looked confidently at the camera over her shoulder, reports people.com.

"Feeling like superwoman after the show tonight," Lopez wrote. In the caption, Lopez reflected on her jam-packed show at Planet Hollywood in Las Vegas, which comes to a close on September 29.
