If you had tickets to “Pour It Up” with Rihanna tonight in Houston, you might be a bit disappointed. According to concert promoter Live Nation, the singer will have to cancel her Houston stop due to illness. Fans have been asked to hold onto their tickets as the date will be rescheduled and the tickets purchased for tonight’s show will be honored.

There’s no word on whether or not her Dallas show scheduled for tomorrow night will go on as planned.
