Beyonce :: Cliff Watts/SI
Happy birthday Beyonce. Hard to believe it's been six years since the Texas native appeared on the cover of SI Swimsuit's 2007 music issue. At the time, Beyonce was still a single lady hoping boyfriend Jay-Z would put a ring on it. Since then, the two have gotten married, given birth to a daughter and become one of the most talented husband-wife duos in music history. The two are celebrating Beyonce's big day in Spain with 19-month old Blue Ivy. So here's to Beyonce. She's pretty much conquered the world so we're not sure what we could wish her for her birthday but we hope it's a good one.
