You must have thought Rihanna was kidding when she said, "That Rihanna reign, just won't let up". We didn't. She joins the ranks of Beyonce, Mariah Carey and Lady Gaga tying them for the most number one hits on the Pop charts. She's had six chart toppers since 2006 and she's showing no signs of slowing down. Her first was "SOS" in 2006, "Take a Bow" in 2008, "Disturbia" in 2008, "Live Your Life" in 2008, "Rude Boy" 2010, and her latest number one comes by way of Eminem's "Love the Way You Lie."
