She’s known for rigorous routines on and off the stage.

And Jennifer Lopez certainly brought the heat to Miami as she was spotted leaving the gym in a daring pink crop top and leggings on Tuesday afternoon.

The 49-year-old entertainer looked supremely fit in her workout wear after beginning round two of her extreme no-sugar, no-carb 10-day diet with boyfriend Alex Rodriguez.

Lopez showed off the fruits of her labor wearing a tiny pink top with long sleeves and sheer panels on her shoulders.

Her high-waisted grey leggings hugged her hips and featured see-through material running down her legs.

Alex broke a sweat during their fitness routine as he left wearing a navy shirt and matching track pants.

In addition to the his-and-hers workout at the UFC Gym, the couple were joined by Olympic swimmer Ryan Lochte and pregnant wife Kayla Rae Reid.

Alex and J Lo recently brought their Instagram followers along for the ride as they endured an extreme 10-day no-carbs, no-sugar diet earlier this month.

And just weeks after completing their strict regime, it looks like the A-list couple is cutting back once again, at least according to an eagle-eyed insider who spoke to Page Six after seeing the pair at a University Of Miami baseball game on Saturday.

During their stop by the ball field, which is named after the MLB alum, they were spotted turning down the famous Mark Light Shakes, causing many to think the duo are dieting again.

Both Lopez and Rodriguez, 43, completed the 10-day challenge at the end of January, after which they treated themselves to a massive feast.

Rodriguez shared a snap on Instagram on January 31 with their huge spread of food, which included several pizzas, a huge plate of chicken wings, fries and pastries.

Lopez even hinted right after the challenge was over that she was going to try again very soon, on her Instagram story.

‘Alex and I struggled through. Anyone who has stuck with us through the ten day challenge, congratulations,’ Lopez said at the end of January.

‘Maybe we’ll stop for a few days and then get back on it, and some of you can join me for the second round,’ she teased.

During her first 10-day challenged, she even encouraged a number of her friends to join such as Leah Remini, Elaine Goldsmith-Thomas, the president of her production company, Nuyorican, and Hoda.

The diet comes as Lopez has been training for her role in The Hustlers at Scores, where Lopez will play a stripper.

Rodriguez took a video featuring Lopez doing some pole dancing training on his Instagram story on Monday.

The Hustlers At Scores is based on the true story of a number of strippers from the New York City strip club Scores.

The dancers would get their revenge on their drunken, wealthy clients by maxing out their credit cards while they were passed out.

Lopez will star alongside Constance Wu, with Lorene Scafaria writing and directing, based on a 2015 New York Magazine article by Jessica Pressler.
