Things have not been going according to plan for Rihanna on her Diamonds World Tour. Apparently still recovering from laryngitis and the flu, the singer has decided to cancel a second straight show, tonight in Baltimore. On Sunday, Rihanna cancelled her show in Boston, the second stop on what is scheduled to be 71-stop world tour. A statement from Live Nation suggests that fans should hold onto their tickets "pending rescheduling show date information."

Rihanna's next scheduled tour date is Thursday, March 14 in Philadelphia. No word on the status for that show.
