Singer Rihanna performs onstage during the 55th Annual Grammy Awards on February 10, 2013 in Los Angeles, California.
Rihanna has canceled another stop on her tour because of the flu and laryngitis.
Her representative said the singer's show in Baltimore on Tuesday would be postponed. Rihanna canceled her Sunday show in Boston because she was sick. Her "Diamonds World Tour" launched in Buffalo, N.Y., on Friday.
Live Nation said in a statement that "Rihanna is still recovering." The concert promoter said fans "are instructed to retain their tickets pending rescheduling show date information."
The next date on Rihanna's tour is Thursday in Philadelphia. She's supporting her seventh album, "Unapologetic," which features the hits "Diamonds" and "Stay."
