Rihanna flies back to Barbados for grandmother's second memorial

Rihanna jumped on a plane following her performance in London on Sunday and headed back to her native Barbados for the second time in a week to continue mourning the death of her late grandmother.

The Umbrella star was left devastated when her beloved Clara 'Dolly' Braithwaite passed away on 30 June and she scrapped a scheduled performance at the Rock in Rio festival in Madrid, Spain last Thursday to allow her time to grieve her loss with her mother's family back in the Caribbean.

She then flew to New York, where Braithwaite lost her battle with cancer, and attended a funeral service in her memory in Brooklyn on Friday.

Rihanna jetted to London soon afterwards to honor her commitment to the U.K.'s Wireless Festival on Sunday, but she was back on a plane headed west on Monday morning for another memorial in Barbados.

Taking to her Twitter.com page to blog about her jetsetting lifestyle, she wrote, "grangranDOLLY time for your party in Barbados".

An official funeral for Braithwaite will be held at Emmanuel Baptist Church in St. Michael on Tuesday.
