a domestic violence case between Rihanna and her boyfriend, the American entertainer Chris Brown, media speculated as to whether any song on her fourth studio album would be about him. The album was released in November 2009, under the title Rated R. Primarily a pop and R&B album, it also incorporates elements of hip hop, rock, and dancehall. Rated R was commercially successful and spawned six singles, including the international hit, "Rude Boy". Six months after releasing the record, Rihanna began planning a fifth studio album, promising that her new material would be "more energetic" than her previous works. Stargate's Tor Erik Hermansen, said "Rihanna came to us before we started recording 'Only Girl (In the World)' and said 'I feel great about myself.

Singer-songwriters and producers Taio Cruz, Alex da Kid, Sean Garrett, Ne-Yo, Rico Love, Timbaland, Shontelle, David Guetta, and Drake contributed to the album.
