If there was to be a real-life case of ‘Benjamin Button‘ — Jennifer Lopez would be it, defying her age at nearly 50-years and looking like a complete knockout.

The hot mama looked in tip-top shape as she walked to the gym wearing a cropped VS tank top, blush pink metallic Niyama Sol leggings, and white sneakers.

The ageless-beauty looked stunning carrying a rhinestone studded reusable cup as she walked to the gym with a bodyguard after revealing she had to perform with a fever during two of her concerts in her It’s My Party Tour diary.

JLo got candid about getting sick while having to work and revealed she performed while running a fever — ‘I feel much better today, I don’t have a fever like I did the last two shows and my voice doesn’t feel as raw’ — she said while laying down and drinking tea and sitting next to a humidifier.

The singer got a bit emotional after her Las Vegas show but had her supporting fiancée Alex Rodriguez to pump her up when she was feeling down, telling her and her backup dancers — ‘It was the best show I have seen so far!.
