JENNIFER Lopez proved she still has an absolutely knockout figure when she took to the stage for her Super Bowl performance on Sunday.
The popstar looked better in a skimpy get-up at the age of 50 than she did in 1997 - despite three divorces, a set of twins and countless heartbreaks.
And many of her fans were left asking exactly how J-Lo has managed to get such an incredible physique at her age.
Here, we take you through the main ways the actress and singer keeps the weight off and stays so incredible toned.
Jen uses a combination of fitness techniques - including avoiding processed foods and pole-dancing...
1. Ditch coffee and stay hydrated
J-Lo makes sure she drinks plenty of water, especially before a workout, to help stay in shape.
She told Hello!: "I try to keep my body hydrated and well rested after every workout. That way, I’m ready to hit it hard again the next day."
Not only does drinking water after a workout help repair your body, but staying hydrated helps replenish skin tissues which helps with elasticity as you age.
2. Say no to carbs and sugar
Earlier this year, J-Lo and her boyfriend Alex Rodriguez had revealed they were doing a ten-day ‘no carbs, no sugar’ challenge in a bid to lose weight.
This ten-day challenge is similar to the Keto diet.
So, you increase your intake of protein and fat to replace the carbohydrates and get the required nutrition, then eat mostly healthy proteins, fat and sometimes dairy – aiming to cut out carbs altogether.
3. Stick to proteins and veg
J Lo’s health regime starts on the plate, and she opts for nearly everything being organic.
For lunch, a typical meal will involve a salmon salad, or broccoli, peppers, and courgette drizzled with vinaigrette.
Dinner time consists of a protein-based dish with quinoa or baked yams.
4. Avoid fried foods
J-Lo's personal trainer recently revealed that J-Lo eats only clean food - so you won't be seeing her at the McDonald's Drive-Thru any time soon.
PT Tracy Anderson told People Magazine: "I have her eating very clean because she needs really good fuel for all the things that she’s doing.
"It’s all organic and it’s very well thought out, with the balance of very high quality proteins and a lot of nutrient-dense food… everything is fresh."
5. Snack regularly
J-Lo snacks every two to three hours to support her metabolism.
Unfortunately, we can't say she has a cheeky dairy milk or a bag of Haribo - as she snacks between meals on fresh vegetables.
She told Hello Magazine: "I always carry fruit and veggies with me to give me something to snack on between meals."
6. Have a treat once a week
While J-Lo has an extremely healthy diet, she does let herself reach for a sweet treat every so often.
In particular, she eats a square of chocolate or a cookie once a week.
She also doesn’t believe that you have to be perfect – it is okay to slip up on your routine occasionally.
7. Never skip a workout
As her honed figure shows - J-Lo trains like an athlete, and always gives 100 percent every time she steps into the gym.
The popstar stays motivated by frequently working out with her boyfriend.
She also makes sure she starts the day in the gym to ensure she has enough energy to keep her going.
While filming Hustlers, Jennifer also mastered the art of pole-dancing.
During that time, Jennifer worked out intensively to build the upper body and core strength she needed to support herself on the pole.
She said: "It was more like, the more you can work on the pole, the more you're going to tone the things that need to be toned anyway and you're getting the work done for the movie."
9. High Intensity Interval Training
When Jennifer isn't working out in the gym or dancing, she goes to celebrity trainer David Kirsch in New York for a more high intensity session.
Instead of conventional cardio, the trainer to the stars prefers his clients to do high-intensity interval training.
These can involve anything from kickboxing, circuit training, burpees and lunges - and this particular kind of high intensity training in short bursts has been proven to to increase fitness level and regulate blood sugar which helps you stay trim as you age.
10. Take care of your skin
J-Lo keeps her skin looking so young and flawless with regular facials and never being caught outside without wearing sunscreen.
The singer told InStyle that because she wears a lot of makeup when performing, she chooses not to wear any in her downtime to let her skin rest.
She also credits not spending too much time in the sun as a reason why her skin has maintained its youthfulness.

11. Get plenty of rest
J-Lo revealed that she meditates twice a day to make sure she stays stress free and relaxed.
‘I learned transcendental meditation this year because it’s overwhelming at times. Doing all of the things I do, at once,’ she told US Weekly.
Typically, she will meditate once in the morning and once at night.
