Rihanna has never been the biggest or best performer, but she is a major star. So, this is why this is rumor worthy. She just kicked off her international “Last Girl On Earth” tour and had to scrap several dates! Why? They are saying that the venues are not selling well, even though she has fake Gaga Kei$ha on the tour with her. Her promoters are sagging that production changes are the real reasons but…eh. Sounds lame. Overall, concert revenue is down in 2010.
