The music industry's most powerful duo started dating way back in 2001 but kept their love tightly under wraps. Jay-Z and Beyonce collaborated in the studio, which led to a close friendship, mutual respect, and eventually an incredibly private relationship. It was the release of their 2002 song, "03 Bonnie and Clyde," that hinted they might be romantically involved, but the singer and rapper adamantly denied that they were anything more than "just friends." Finally, in 2008, they wed in a private ceremony. Though the recent birth of Blue Ivy has brought the happy family into the public eye, Jay and Bey are a far cry from, you know, Kimye.
