Why we loved her in 2010: In the midst of completing her I Am. . . world tour, our girl Beyonce set a record for most Grammy wins by a female artist in one night (a total of six, including Song of the Year for "Single Ladies" and Best Contemporary R&B Album for I Am. . . Sasha Fierce). Her surprise appearances during Jay-Z's performance at Coachella and Alicia Keys' Freedom Tour fueled the hype perpetually surrounding Ms. Knowles, and the unrelenting pregnancy rumor and being consistently bootylicious might've had something to do with making her year a solid '10, too.
