Rihanna's fourth studio album "Rated R" was released in November 2009. The album debuted at number four on the US Billboard chart, selling 181,000 copies in its first week. This was Rihanna's highest first-week sales in the US at that time. The album cover features a black and white close-up image of Rihanna with heavy makeup, giving a challenging stare. It does not include her name but has the letter "R" to signify the album title and its explicit content. Both the CD and back cover continue the theme through the letter "R" and images of Rihanna that create a sense of sex appeal.
