The Barbadian pop-superstar Rihanna was put a 24-hour health watch by her concerned handlers.

Mercury Records execs grounded the 23-year-old singer after she apparently had an episode and almost cancelled a tour date in Dublin, Ireland.

Basically, since Ri Ri has been on tour all year to supplement the lackluster sales of her latest project — which is not an indictment of her album, but of the record industry in general — her investors wanted to give her a day off.
