Singer Rihanna, a Barbados native, has been ordered by her doctor to cancel three shows on her U.K. tour, on December 8, 10, and 11. Those who have tickets should hold onto them until later – the shows might be rescheduled at a later date.

In the meantime, Rihanna says she “appreciates the love and support of all her fans and wants nothing more than to see and connect with them.”

On Thursday, Rihanna was nominated for six Grammy Awards, and she was also named “favorite female artist” last month at the American Music Awards.
