New York - Rihanna announced on Monday a global tour next year as the R&B superstar undertakes extensive commercial tie-ups in the run-up to her long-awaited next album.
Rihanna will open her tour on 26 February in San Diego, performing a total of 70 shows around North America and Europe before ending on 12 August in Zurich, promoter Live Nation said.
The Barbados-born singer has sold 54 million albums since her 2005 debut but has not released a full-length work since 2012.
Rihanna has said that the new album and tour will be called Anti, although she has not confirmed a release date.
In a promotional deal, Rihanna has formed a partnership with South Korean electronics giant Samsung, which has launched an interactive website for Anti accessible only on its smartphones.
Samsung took out a large number of advertisements for Anti during the television broadcast of Sunday's American Music Awards, hinting that a release is imminent.
For Samsung, the sponsorship of Rihanna would mirror arch-rival Apple's frequent efforts to team up with artists including U2 and Drake.
Rihanna will also make tickets available early for subscribers of Tidal, the streaming service led by rap mogul Jay Z that has emphasized exclusive content from artists as it challenges rivals such as Spotify and Apple Music.
Samsung has not announced details, but the New York Post earlier reported that it had inked a $25 million deal with Rihanna.
