Rihanna made the book for most female #1 singles in the US in a year. Other names in the book include Lady GaGa, Adele, Taylor Swift, Lil Wayne, and umm... Willow Smith (remember Whip My Hair?). Yeah kind of surprised to see her name on the list. That's just an overview, Perez Hilton will give you the specifics: http://tinyurl.com/3q8l5nl
