Everything is coming up Mariah Carey in the city this week: the queen of Christmas joined forces with "that Hanukkah hobgoblin" Billy Eichner to spread some cheer around the city for an all-new episode of Billy On The Street. Carey speaks Swedish, hugs some flustered fans, and fixes a broken Christmas tree; Eichner yells a lot, and the two sing some holiday songs, including the Dreidel Song: "Don't fuck with Mariah's Hanukkah lyrics babe!" Check it out below.

But that's not all: Carey performed a sold-out Christmas-themed show at Madison Square Garden which Schitt's Creek's Dan Levy called "the greatest two hours of my life."

Fans were so hyped up, they started a subway singalong across the platform from one another afterwards (a la Robyn fans).

And to top it all off, "All I Want For Christmas Is You" is projected to go to #1 on the Billboard charts this week.
