Rihanna celebrates her 28th birthday in styleFeb 23(AZINS) R&B star Rihanna celebrated her 28th in style at Via Alloro in Beverly Hills over the weekend despite recent gig cancellations.

The Barbadian superstar, who pulled out of the Grammys last week citing a case of bronchitis as the reason for her cancellation, seemed to be wholly recovered as she partied on February 20th night, reported Radar online.

A picture captioned "Burfffdayy Queennn" has been doing the rounds, featuring her dancing and twerking to Fetty Wap's 'My Way', as she toted an impressively-sized glass of red wine at Via Alloro in Beverly Hills.

Despite the partying, Rihanna's planned promotional tour of North America has been beset by production delays and technical difficulties, as it was announced late last week that the start date of the Anti tour would be March 12 in Jacksonville, Florida, with the eight affected dates re-arranged for late May. Additionally, two British dates were cancelled altogether with no news of possible re-arrangements.

Meanwhile, the 28-year-old singer's music video for 'Work' featuring Drake came out on Monday. It's the first single from her studio album 'Anti' which officially came out January 28 via Tidal after months of anticipation.

The music video shows the 'Umbrella' hit-maker and the 29-year-old rapper dancing to the hit track with other party-goers.
