Mimi you are truly a deluded Rihanna stan if you think she is anywhere near as famous as Beyonce or even Alicia and the rest too. You are in denial sweetie. Beyonce headlines her own sold out tours around the world and so do the other 3. Rihanna is an opening act for Kanye west and she gets all bad reviews. People only talk about Rihanna's style that is it. She cant sing or dance. And Irreplacable was the biggest hit of 2007 so get your facts straight. Rihanna has not made history and has never been the first to do anything. Beyonce and Alicia are tied for most Grammy's won in one night. If Rihanna was on the same level as them then why didnt she win 5 grammy's out of her 6 noms like they did the first time they were nominated? All four of those women have sold over 100 mill records well except Mary and Alicia but Beyonce and Mariah have. They are the top 4 best artists of our time and Rihanna is nowhere near their level, talentwise,famewise,successwise, or anything else. You need a serious dose of reality. You're only 23 so you are still young and clueless. You know nothing about real music and real artists. When Rihanna has even 1/2 as much success as those 4 women then you can compare her to them. You can say what you want but everyone knows this is a fact. Rihanna Ciara and Ashanti are all mediocre artists who will not be remembered years from now. Even with the success of Umbrella Rihanna still has never had a #1 album in the U.S after 3 albums and even Tpain sold more than her on the first week. Rihanna has never sold over 500,000 copies in one week like those 4 women I mentioned. And Rihanna has had 3 albums out. Does that sound like somebody who is on their level on anything? Ummm no. You need a dose of reality for real.
