The "Ain't Your Mama" singer shared a behind-the-scenes look at her recording session with her former flame on her Instagram story, in a video that pans around the studio, showing all the people working on the project.
While she's excited to be back in "the lab" making new music, Lopez was equally excited to see a massive photo of herself on the side of the Empire State Building.
In honor of Harper's Bazaar's 150th anniversary, some of the magazine's most famous images were projected on the size of the iconic NYC landmark, and Lopez couldn't help but fan out when her photo came up.
"Happy 150th Anniversary @harpersbazaarus," Lopez wrote in the caption to a photo she posted of the moment.
Lopez tagged this pic with the totally relatable hashtag, "#Thatmomentwhenyouseeyourselfontheempirestatebuilding."
Lopez and Anthony, who have been working on a new album together, performed on stage together for the pop icon's first concert in the Dominican Republic over the Easter weekend.
Lopez and her boyfriend, Alex Rodriguez, made a vacation out of the experience and brought their adorable kids to the Caribbean island along with them. Check out the video below to hear more about their fun vacay.
