Ariana Grande, Ethan Slater pick out Christmas tree in NYC as couple plans ‘low-key’ holiday together after ‘Wicked’ whirlwind release

They have 359,270,510 reasons to celebrate Christmas this year.

“Wicked” costars — and off-screen couple —  Ariana Grande and Ethan Slater were spotted picking out a Christmas tree in NYC on Sunday, spies said.

We hear they’re spending a low-key holiday together in the wake of the “Wicked” whirlwind release.

A source told Page Six of the duo, “Arianna Grande and her boyfriend, Ethan, [were] buying a Christmas Tree from Yianni Karadimas’ Christmas tree stand on 62nd [and] Broadway,” in Manhattan.

The grand conifer apparently ran the couple $300.

A source familiar with the stars added: “They are celebrating the success of ‘Wicked’ and keeping things low-key as they enjoy the holiday season together.

“Wicked” has reeled in $359,270,510 so far at the global box-office as of Monday, as the biggest Broadway musical adaptation of all-time, and is getting Oscar buzz for Grande as “Galinda.”

A pic posted to Instagram by a fan of the pair picking out their tree showed Grande looking Galinda-like — in an oversize off-white, puffy, belted coat and a light-colored scarf around her head — and Slater in a tweedy overcoat, a grey sweater and a ballcap.

Sources close to the couple tell Page Six that they’re enjoying the holidays after their whirlwind “Wicked” press tour with costar Cynthia Erivo that hit New York, Los Angeles, London, Paris, Sydney, Mexico City and world cities.

Universal’s marketing head had told the Wall Street Journal that the Hollywood studio’s plan was to be “just short of obnoxious” regarding the film’s ubiquity in the marketplace.

And whatever presents Grande, 31, gets under that tree this year, she could get a bigger prize in March as she’s now tipped for an Oscar.

The Post reported that Grande is already looking like an early favorite to win Best Supporting Actress at the 2025 Oscars — while Erivo is set to face fierce competition from Angelina Jolie and Mikey Madison in the Best Actress category, Hollywood sources said.
