Jennifer Lopez kept it radiant in an all-black outfit, but her face was tense…

Four days ahead of her highly anticipated halftime performance at Super Bowl LIV, Jennifer Lopez flashed her enviable abs while on a gym date with her fiancé Alex Rodriguez in Miami, Florida.

The stunning 50-year old kept her game face on while decked out in an all-black ensemble, over-sized frames and Nike sneakers.

On her way into the gym, she held her signature over-the-top bedazzled Starbucks cup and displayed her toned stomach in a form fitting crop top and leggings.

As shown in her recent snaps on Instagram, she poked fun at her love for bling, showcasing another crystal-embellished J Lo cup and matching microphone.

Lopez has given fans an inside look on her vigorous training sessions, which often includes her husband-to-be, and grueling rehearsals.

In September, it was announced that she and Latin singer Shakira would co-headline the coveted Pepsi Half Time show.

Rodriguez often takes to Instagram to compliment and fawn over her strength and sculpted abs, and left their most recent sweat session with a drenched shirt.

The engaged couple have also proven they are equally passionate about nutrition, often cutting sugar and carbs altogether.

Honored: Jennifer describes being able to perform at the Super Bowl is ‘like winning an Oscar’

The singer told CBS performing at the Super Bowl is ‘like winning an Oscar.’

‘It’s the biggest show that there is. It has the biggest audience. You get to have like this big production. You don’t get to do that on tour,’ she explained.

‘I think it’s just like a fantasy for all musical artists to be able to play the Super Bowl and have like that 12 minutes of an amazing show,’ she added.

While she is taking the stage alone, inside the gym the Jenny From The Block singer, like her beau, loves posting couple’s workout videos and nutrition advice.

The fit couple are always pushing each other from boxing to pull-ups and kettlebell swings.

The pair got engaged in March 2019, after two years of dating, but first met when the singer was married to the father of her two children Marc Anthony.

Now, 12 years later, the pair are inseparable.

On Entertainment Tonight, she revealed the timing of their relationship is perfect, because it wouldn’t have worked out so well in their twenties.

‘We were both at a good place in our lives and I think, maybe if we had met in our 20s, it wouldn’t… you know, maybe not so much,’ Jennifer said, admitting that both she and Alex were ‘too crazy’ when they were young to have made things work.

“But now, at this point in our lives, where we both have kids and we both accomplished certain things in our careers and we’re kind of in that second act of our lives,” she said.

‘We really complement each other,” she added, before their engagement.

In addition to her twins Emme and Max, 11, Alex has three girls, Natasha, 15, and Ella, 11.
