Hilary Duff is big. Mariah Carey is bigger.
As Duff's Most Wanted logged its second straight week atop the album chart, Carey made history again over on the singles chart. Already tops among female artists with 16 Billboard number ones, Carey became the first female artist to lock down the number one and two positions, with her mega-hit "We Belong Together" marking its 14th week atop the Billboard Hot 100 and her new single, "Shake It Off," right behind.
The tracks come from The Emancipation of Mimi, which remains a Top 10 fixture on the pop album charts, finishing last week at number three with 89,000 in sales, according to Nielsen SoundScan figures, behind only Duff's best-of set (101,000) and Now That's What I Call Music! 19 (96,000).
