The 51-year-old singer is believed to have rekindled her romance with the Good Will Hunting actor, 48, 17 years after their shock split in 2004.
The speculation comes after the former love birds were pictured enjoying what looked like a romantic break in Montana , where Ben owns his own chalet.
After returning from the getaway, it seems as though Jen wants to throw herself back into a routine as she was seen heading to the gym on Wednesday.
J-Lo kept a low profile on her route as she donned a huge pair of oversized sunglasses which covered her face, and she also made sure to wear a face mask.
The singing sensation slicked her hair back from her face into a low bun as she prepared to work up a sweat in the gym.
Jennifer also kept it low-key in the wardrobe department as she donned a loose-fitted white t-shirt and some colourful yoga pants which did wonders to accentuate her famous curves.
It comes just a few days after Ben were spotted driving his SUV with Jennifer sitting close-by in the passenger seat.
“They were alone,” a source told E! . “Just the two of them.”
Lifting the lid on their current relationship, the source added: “They have been in touch here and there throughout the years.
“Ben reached out to her to see how she was doing and they had dinner together a few times within this last month. It’s natural between them and the chemistry is unreal.
“They picked up where they last left off and are enjoying each other’s company right now.”
