Jennifer Lopez thinks her health-conscious approach to life "shows" through her appearance.
The 49-year-old star has made a concerted effort over the years to eat well and ro remain in tip-top condition, and Jennifer feels she's now seeing the benefits of her self-discipline.
She shared: "I've taken care of myself, and now it shows."
The 'Jenny from the Block' hitmaker - who is currently dating retired baseball star Alex Rodriguez - has always been a hard worker.
But Jennifer no longer feels she really needs to prove herself to anyone else.
She told InStyle magazine: "When I first started, it was always a matter of 'Am I good? Am I good enough? Do I need to be better? What can I do to be better?' Now I know I'm really good at this. So I just want to do it."
Jennifer claimed earlier this year that she's in the "best shape of her life".
The chart-topping singer said she feels like "Superwoman" now because she's so "strong, happy and grateful".
Just before the end of her residency in Las Vegas, she wrote on Instagram: "Feeling like superwoman after the show tonight! When I started this run I thought omg 15 shows in 27 days that's a lot ... but I made a promise to myself that instead of letting it wear me down I would be even stronger at the end of it ... I will work out and be in the best shape of my life.
"There were moments I was tired and there was travel and I had to fit in my workouts where I could ... but here we are with only 3 shows left!! And I am having so many emotions but mostly just feeling strong, happy and grateful!!! (sic)"
