Thanks to "All I Want For Christmas Is You" finally going to number one for the first time in 25 years last week, Mariah Carey has set an all-time record.
On the Billboard Hot 100 Chart, Mariah is the only artist with a number one hit in four different decades. That would be 90's, 00's, 10's and 20's, as we roll into 2020.
Eight other artists have had a number one hit in three different decades, including Stevie Wonder, Elton John, Michael and Janet Jackson and Madonna.
In case you were wondering, Mariah has had 19 #1 songs on the Billboard Hot 100 Chart.
