In 2002, her album "Charmbracelet" was released. Her 2005 album, "The Emancipation of Mimi", became one of her most successful albums. Many music critics believed it was her "comeback album". It contained her sixteenth and seventeenth US number-one hits, "We Belong Together" and "Don't Forget About Us". "We Belong Together" was the number-one song of 2005 and of the 2000s decade in the US. Her following album, "E=MC²" (2008), featured her eighteenth number-one song, "Touch My Body". With this, Carey holds the most US number-ones for a solo artist in history. However, this album, along with its followups "Memoirs of an Imperfect Angel" (2009) and "Merry Christmas II You" (2010), did not sell well. She played the role of a social worker, Ms. Weiss, in the 2009 movie "Precious".
