At one point, the duo was spotted holding hands inside, too, and they appeared to be laughing and in high spirits when they exited.

J.Lo looked très chic in an oversize white button-up shirt and baggy dark-wash jeans layered under a black trench coat.

The pop star pulled her outfit together with casual while sneakers and a white Hermès Birkin bag.

Wearing her hair loosely pulled back in a ponytail, she also accessorized with big white and gold sunglasses and large gold hoop earrings.

Emme, meanwhile, looked cool and laid-back in a textured pink button-down tee, mid-rise barrel jeans and navy Converse sneakers.

Lopez and Emme also were spotted strolling through the Marais district of Paris and dining at the posh restaurant LouLou.

The Grammy nominee’s artful outing comes just days after she co-hosted the 2024 Met Gala in New York City.

She attended the star-studded event Monday night wearing a custom Schiaparelli Haute Couture gown covered in rhinestones and pearls.

The sheer mermaid-style gown took 800 hours of hand embroidery work to complete.

Lopez was also dripping in more than 100 carats of diamonds by Tiffany & Co. for the fashion fundraiser.
