Mariah Carey‘s welcome to the Christmas season is here. The “All I Want for Christmas Is You” hitmaker made an official announcement to kick off the holidays in partnership with Sephora.

“Halloween slayed,” Carey says in the Joseph Kahn-directed ad that dropped as Halloween (Oct. 31) came to a close. “But now … it’s time!”

There’s one problem: Someone’s rummaged through the pop diva’s Sephora bag and pilfered the new beauty goodies she snagged for the 2025 holidays.

In the lighthearted spot, Carey demands someone spill the tea on who stole her makeup so she can ring in the season of her modern Christmas carol, and — spoiler alert — it’s not the Grinch.

It’s Billy Eichner as an overworked elf advocating for better treatment at Christmastime.

“Bad news, Mariah Carey,” the comedian taunts. “The elves are striking this year. Elf revenge for putting us through holiday hell! Santa’s helper quit. I’m pawning this so I can afford elf therapy!”

“That’s my blush, elf boy,” Carey says.

“Your lipstick? I’m taking it. No bells. No cheer. No glam. Bye, sweetie,” Eichner throws back.

The Christmas commercial comes right after Carey dropped a collection of holiday merch, like a snow globe that plays “All I Want for Christmas Is You”; a Christmas sweater, earmuffs, socks, pajamas, robe and slippers; ornaments and stockings; holiday baking supplies and a large inflatable lawn decoration. Mariah might not “want a lot for Christmas,” but she’s given fans plenty to add to their Amazon wish lists.

Oh, and go ahead and press play on her classic “All I Want for Christmas Is You,” the song that Christmas music lovers have listened to enough to make it Carey’s longest Hot 100 reign (with 18 total weeks at No. 1, four of which were just last year).
