A while back, Rihanna canceled a concert in Boston because she had laryngitis. She rescheduled the concert for the other night, but she didn't make fans happy. She was three hours late--and there was no opening act.
Angry fans tweeted out and said things like "I'm over her" and "Thank you @rihanna for playing an hour long concert and lip syncing the whole thing. I'm glad u 'balled out' for Boston."
Other people on Twitter disagreed and said it was a great concert with a nice Boston tribute.
