Unapologetic is the seventh studio album by Barbadian singer Rihanna. It was released on November 19, 2012, by Def Jam Recordings and SRP Records. It was recorded between June and November 2012, during promotion of her sixth album, Talk That Talk (2011). As executive producer, Rihanna enlisted previous collaborators The-Dream, David Guetta, Chase & Status, and StarGate to work alongside new collaborators such as Parker Ighile, Mike Will Made-It, and Labrinth. Unapologetic is mainly a pop, dubstep and R&B album that incorporates elements of hip hop, EDM and reggae in its production, similar to the sound of her previous albums Talk That Talk and Rated R (2009).
Unapologetic received generally mixed reviews from critics, with some reviewers describing its music as interesting, while others criticized its lyrical content and rushed nature. The album won the Grammy Award for Best Urban Contemporary Album at the 2014 ceremony. It debuted at number one on the US Billboard 200 with first-week sales of 238,000 copies, becoming Rihanna's first number one album on the chart and best-selling debut week of her career. The album also became the singer's third, fourth, and fifth consecutive number one album in the United Kingdom, Norway, and Switzerland, respectively. As of December 2014, Unapologetic has sold over four million copies worldwide.
The album produced seven singles including the international hits "Diamonds" and "Stay". The former peaked at number one on the UK Singles Chart and the US Billboard Hot 100 where it became Rihanna's twelfth number one song, tying her with Madonna and The Supremes for fourth most number one songs in the history of the chart. Prior to its release, Rihanna promoted the album with the 777 Tour which consisted of a seven-date promotional tour in which she performed seven concerts each in a different city in North America and Europe in seven days. To further promote Unapologetic, Rihanna embarked on her fourth worldwide tour entitled the Diamonds World Tour.
