Barry Keoghan and Sabrina Carpenter Look 'Cute' Together During Date Night in L.A. (Exclusive Source)

The pair stepped out for a low-key date night on Saturday at Luna Luna, an art amusement park

Barry Keoghan and Sabrina Carpenter are spending time together.

The Saltburn star, 31, and the singer, 24, enjoyed a night out together in Los Angeles on Saturday as they stopped by Luna Luna — an art-centric theme park that recreates the original 1987 art amusement park in Germany — a source confirms to PEOPLE.

"It definitely seemed like a date,” an onlooker tells PEOPLE of the pair’s outing, which comes after weeks of speculation about them possibly being an item.

Keoghan and Carpenter were “cute” together and “shared a little kiss,” the onlooker adds of their outing to the new L.A. art scene hotspot.

PEOPLE reached out to Keoghan and Carpenter's reps for comment.

The night out comes after a big week for the Irish actor, who attended last week’s Golden Globes Awards, where he was nominated best for performance by a male actor in a motion picture - drama for Saltburn. Keoghan also celebrated another forthcoming project, Apple TV+’s Masters of the Air, at the L.A. premiere on Wednesday.

At both events, he brought his style A-game. He wore a red suit jacket and checkered trousers with some chains at the awards show, and rocked an off-white sleeveless suit set from Dolce & Gabbana at Wednesday's premiere.

Carpenter, meanwhile, has been lying low in between runs supporting Taylor Swift on the international leg of her record-breaking Eras Tour. She kicked off her slate as an opening act on the tour for three dates in Mexico City in August, followed by a run of South American shows in Argentina and Brazil.

After Swift, 34, plays four shows in Tokyo in early February, Carpenter will join her again for a run of dates in Australia and Singapore.

The “Nonsense” singer told Who What Wear in November that the gig is a “childhood dream come true” for her. “I still probably have not processed it if I’m being completely honest with you," she said.

Keoghan and Carpenter’s blossoming relationship comes after the Irish actor made his first comment following reports that he’d split from his longtime girlfriend Alyson Sandro, with whom he shares a 1-year-old son, Brando.

“She’s done a great job and she’s an incredible mother,” he told GQ of his former partner.

Carpenter has been previously linked to Shawn Mendes and briefly dated Joshua Bassett, a relationship many fans speculated to be the basis for Olivia Rodrigo’s breakout hit “Driver’s License.”
