Rihanna enjoyed a cold one while on a boat ride in her native Barbados Thursday, and we've got the shots for you right here on Breaking Celebrity News.

Although the Disturbia singer, 24, looked in good spirits as she went tubing behind the power boat, she’s still mourning her late grandmother Clara Brathwait, who died last week after a battle with cancer.

The Only Girl singer tweeted to her 22 million followers Thursday, "#grangranDOLLY I know you smiling down on me brightly, I could feel it in the sunshine ?#1Love forever."
