Rihanna has been showing exactly how you party to excess this week on a luxury yacht on the Mediterranean.
However, according to a source close to her and her family, those closest to her are concerned that her hard partying is a sign that she is struggling to cope with the grief she feels following the recent death of her grandmother Clara Braithwaite, known fondly as GranGran Dolly.
The star has been boasting about her partying antics on Twitter since she took to the seas last weekend, and while she appears to be having the time of her life, drinking, dancing and bathing in the sun, with her grandmother's death only a few weeks ago those close to her fear she isn't coping.
"Rihanna was super close to her grandma," an insider told RadarOnline.
"Rihanna is using the partying as an escape so she doesn't have to deal with the loss of her grandma,"
"She just can't deal with it,” they claim.
Her grandmother had been suffering for cancer in the months running up to her death and Rihanna took time out from her hectic shedule and made an effort to fit in several visits to New York to be with.
After her funeral the star posted a picture of herself looking teary-eyed while clutching a beer implying that she was using alcohol to cope. She posted the pic along with the message: “I had to!!! Sorry granny”
