Duff hasn't hit the Hot 100, or the Billboard 200 with new material, since 2007. She's been in the news of late, however: she'll play Ashton Kutcher's character's girlfriend on the season finale of CBS' "Two and a Half Men," set to air on May 9.
Since releasing her last album, 2007's "Dignity," she's also published two fiction books on Simon & Schuster.
As we await her next album, for which no release date has been announced, here's a look at her career U.S. studio album sales, according to Nielsen SoundScan:
Sales, Title, Year, Billboard 200 Peak
3,996,000, "Metamorphosis," 2003 (No. 1, one week)
1,798,000, "Hilary Duff," 2004 (No. 2)
1,488,000, "Most Wanted," 2005 (No. 1, two weeks)
477,000, "Santa Claus Lane," 2002 (No. 154)
410,000, "Dignity," 2007 (No. 3)
Duff's career U.S. album sales stand at 8,287,000. Not part of the total are soundtracks to hit films in which she's starred featuring her songs, including 2003's "The Lizzie McGuire Movie" (2 million) or 2004's "A Cinderella Story" (649,000).
