The star’s next look was a total Jenny from the Block throwback: black leather harem pants, a shiny top and exposed bandeau. And finally, she took it to Black Tie J.Lo, wearing a a black sheer lace midi dress with slightly-exposed briefs. She teamed the look with lace-up open-toe booties and a sleek blowout.

If she looks more radiant than usual, it’s because she’s feeling great in her own skin — and has been sharing her feelings on aging with the universe.

“This is good for women,” she told The Insider of her sexy new music video for “Booty” in which she co-stars (and goes butt-to-butt) with 24-year-old rapper Iggy Azalea. “You have to know that you don’t disappear after you’re 28 years old. You can be here, you can be vital and young and sexy and feel good about yourself.”

Her secrets for staying in such great shape? Well, turns out they’re not so secret — it’s all about the right mix of diet and exercise.

“Nobody can escape the hard work that it takes to get results,” she shared. “All of us have to work hard at it and I definitely have to.”
