Life changed for Jay-Z when his wife, Beyoncé Knowles, welcomed their first child in January. Baby Blue Ivy Carter was rapidly integrated into Jay and Beyoncé's jet-setting life and has already racked up frequent flier miles to the Caribbean and Europe. Blue also inspired Jay to write the song "Glory." Aside from his growing family, Jay-Z was busy promoting his Watch the Throne album with collaborator and friend Kanye West. The guys kicked off a world tour that's seen them travel through the US and abroad. In Jay’s hometown of NYC, he spearheaded the initiative to build a new stadium for the Brooklyn Nets. He was also involved in a variety of business ventures, from the rejuvenation of his Rocawear brand to D'Ussé cognac.
