On Saturday, the couple was pictured together for one of their first times out together.

The singer and Broadway star were photographed during a night out in New York City when a source close to Grande told PEOPLE they ate dinner with her father Ed Butera at her family’s favorite Italian restaurant before seeing Slater in Spamalot.

Grande sported an all-black with a furry bucket hat, mini skirt, and black top with furry cuffs. Meanwhile, Slater opted for a more athletic getup with a zip-up, joggers and running shoes.

"They love to support each other in their work," the source said. "When she’s done with work, Ariana loves going to the theater when she can."

Grande shared a carousel of photos to Instagram earlier this month, which featured one image with a Spam can ornament hanging on a wall Christmas tree made of green garland.
