The holiday tune quickly became a hit and topped the Billboard's Adult Contemporary pop countdown in just two weeks.
Pregnant Mariah Carey is making history in the U.S. charts - she has become the first artist to top Billboard's Adult Contemporary pop countdown in two weeks or less in 20 years. While most performers crawl to the top spot, Carey has claimed the number one just two weeks after releasing her new Christmas hit "Oh Santa!"
Her festive album "Merry Christmas II You" has also become the first holiday release to debut at the top of the Billboard R&B/Hip-Hop Albums chart since 1994.
"Oh Santa!" has been heavily promoted since its release and benefits the holiday season. Carey performed the tune during Rockefeller Christmas Tree Lighting earlier this month and has taped a segment for TV special "Disney Parks Christmas Day Parade", singing the song.
