Katy Perry is capping off the year with her new Christmas single, which topped the US Adult Contemporary chart.
The pop star released the original seasonal tune, Cozy Little Christmas, exclusively on Amazon Music in November and it has slowly made its way up the charts to land in the top spot just in time for the big day.
Co-written with acclaimed pop producers Greg Wells (Adele and Dua Lipa) and frequent collaborator American-Jordanian Ferras Alqasi (who worked on Perry's latest album Witness), the track is the kind of perky-pop Perry specialises in.
Written about a former family Christmas holiday in the Danish capital of Copenhagen, Perry urges St Nick to "take the day off, get a massage, "cause we've got this one under control".
Perry's up-tempo effort dislodged John Legend's own Christmas tune from the top spot.
The soul music star teamed up with jazz singer Esperanza Spalding for a relaxed take on the standard Have Yourself a Merry Little Christmas, which reigned supreme on the chart for the last three weeks.
These tracks join a long list of chart-topping Christmas number-one singles recorded by a variety of modern pop stars. Here are five to get you in the festive spirit.
Aussie pop star Sia lent her powerful vocals to Santa's Coming For Us, an original ditty that reached number one last year.
US crooner Josh Groban made smooth work of Have Yourself a Merry Little Christmas in 2016.
1970s pop legends Hall & Oats also scored big with their take of the 1849 Christmas Carol It Came Upon a Midnight Clear. The track became their second adult contemporary chart topper in 2006.
Canadian crooner Michael Buble ruled the chart for five weeks in 2011 with his version of Mariah Carey's 2004 seasonal hit All I Want for Christmas is You
Kelly Clarkson also struck gold with the effervescent Underneath the Tree, the original song taken from her 2013 Christmas album Wrapped in Red.
