ABU DHABI — Rihanna is set to return to Abu Dhabi for her “Diamonds World Tour” in October, organizers announced on Thursday. Flash Entertainment in association with Live Nation Global Touring will bring chart-topping Rihanna to the city on October 19. The recipient of six Grammy Awards and seven Billboard Music Awards, Rihanna currently holds the record as the top-selling digital artist of all time for her sales of 41 million albums and 150 million digital tracks. Forbes recently tagged Rihanna as the world's number one social media star with over 2.9 billion views on YouTube/VEVO, which is the most ever for any female artist. The “Diamonds World Tour” is the Barbadian pop-star's fifth concert tour and was launched to support her seventh studio album “Unapologetic.” Mick Stingley said:“Rihanna is arguably the biggest pop star in the world. At only 25 she has recorded seven albums in less than ten years and sold millions around the world; she's more than a household name, she's a brand.” — Al Arabiya
