If you’re traveling around London, you may hear a familiar voice on public transportation. Mariah Carey, also known as “The Queen of Christmas” has teamed up with Amazon Music to promote her holiday classic All I Want For Christmas.

She’s telling residents and worldwide visitors riding the city’s Underground to “stand behind the yellow line.”

“Hi Dahlings, It’s Mariah,” the announcement begins. “Make my wish come true and please stand behind the yellow line at all times. Proceed with caution. And don’t forget to ask Alexa to play ‘All I Want For Christmas’ on Amazon Music.”


Carey’s Underground London performance comes just weeks after the release of her new Christmas special, Mariah’s Christmas: The Magic Continues.

The festive musical event was released on Dec. 3 via Apple TV+.  Carey collaborated with Khalid and Kirk Franklin for the first and only performance of their new single Fall In Love At Christmas.


According to NME, Carey’s special on Apple TV+ also comes amid her original collaboration with the streaming platform, Mariah Carey’s Magical Christmas Special, which first launched in 2020. Narrated by Tiffany Haddish, the event brought in musical guest stars Ariana Grande, Jennifer Hudson, and even Snoop Dogg.

It’s worth noting that she’s not hailed the Queen of Christmas for nothing. Her holiday song, All I Want For Christmas, consistently ranks Number 1 on Billboard’s Greatest of All Time Holiday 100 Songs list.

Carey recently announced that the song is RIAA Diamond Certified with more than 1 billion worldwide streams.
