Mariah Carey has scored her 16th number one on the US singles chart with the ballad We Belong Together.
Carey's latest album has been a best-seller in the US
The track, taken from her latest album The Emancipation of Mimi, knocked Gwen Stefani's current single Hollaback Girl from the top spot.
Carey now has the third highest number of chart toppers in the US, with only the Beatles and Elvis scoring more.
The Emancipation of Mimi has sold more than two million copies in the US since it was released in April.
It has been in the top five of the Billboard album charts every week since its release.
"I didn't know what to expect when I put this record out except I knew it was a good record and I was happy with it," Carey said.
Carey's comeback has been billed as "the return of the voice" following her struggle to regain the huge success she enjoyed in the 1990s.
The singer's previous album, 2002's Charmbracelet, had disappointing sales, as did the soundtrack to her 2001 film Glitter.
