R.O.S.E. is the fourth studio album by English singer-songwriter Jessie J. It was released by Republic Records in four parts, starting on 22 May 2018, and finishing on 25 May 2018, with a part being released on each day. The four parts released are R (Realisations), O (Obsessions), S (Sex) and E (Empowerment). Jessie co-wrote the album and worked with producers such as DJ Camper and Kuk Harrell. The songs "Real Deal", "Think About That", "Not My Ex" and "Queen" were released as singles before the release of the album.
Following the release of Jessie J's previous album, Sweet Talker, she began to have difficulty with writing and creating new music. In an interview with Billboard, she stated "I wasn't enjoying the music I was making as much as I should. I wasn't writing because I didn't want to make music that escaped me from that. I wanted to make music that put me in the feeling. But to do that I had to be really strong; to know that I wasn't going to be able to be pushed and fall over. That's why it took me a long time. I don't feel that I've ever learned so much about myself at any other time in my life." After some time off working with DJ Camper, Jessie J became inspired to write again. "[DJ Camper] put the "Think About That" beat on repeat before going outside for a break. I called him a dickhead because I still didn't feel creative yet. I hadn't really written a song for two years, just some poetry. But as I sat there and listened to the beat, words started to come out."
In August of 2017, Jessie teamed up with M&M's to promote her single "Real Deal". In the following months, she released "Think About That", "Not My Ex" and "Queen" as follow-up singles from R.O.S.E.
On 15 September 2017, Jessie J announced a worldwide run of intimate shows. On 20 September 2017 an extra date was added in London at the Shepherd's Bush Empire. Jessie J continued to add more dates through 2018 supporting R.O.S.E.
