Jennifer Lopez and Alex Rodriguez got close on the "Shades of Blue" set this week.
Us Weekly reported Lopez was shooting an overnight scene for the show.
The "World of Dance" judge, who plays Det. Harlee Santos, was all smiles in a curly wig, grey sweater and jeans as she posed for photos with Rodriguez.
Rodriguez followed up Thursday by sharing a picture on Instagram of Lopez in costume. The snapshot shows the actress posing on a bed in a white henley and ripped jeans.
"Surprise visit from my favorite detective. #harlee," the former New York Yankees player captioned the photo.Rodriguez had posted a video Wednesday of his morning workout with Lopez, which featured the pair doing "This is Us"-style pushups. The couple were first linked in March, and confirmed their relationship the same month.
"Those in J. Lo's inner circle see her relationship with A-Rod going the distance," a source told Entertainment Tonight this week. "They definitely see marriage potential here."
Lopez shares twins Emme and Max with ex-husband Marc Anthony, while Rodriguez is parent to daughters Natasha and Ella with ex-wife Cynthia Scurtis.
"Shades of Blue" was renewed for a third season in March.
