The A-list couple recently took part in a 10-day challenge in which they gave up sugar and carbohydrates. The pair also challenged their friends, mainly Today show co-anchor Hoda Kotb to join them.
On Thursday, Lopez took to her Instagram Stories to celebrate the final day of the challenge.
"I just got back from the gym. It's day 10. Day 10! We did it, we're here. I mean, we still have the rest of the day, but I'm feeling pretty good, like we can finish,” she told her fans. "Alex and I have struggled through. Anybody who stuck with us congratulations."
She also implied that they would be returning to the challenge soon, saying, "Maybe we'll stop for a few days and then get back on it. Some of you can join me for the second round. Super happy, super proud. We did it!”
