Was rapper Shawn “Jay-Z” Carter an undercover serial dater? Should we have taken his single “Girls, Girls, Girls” more seriously? Of course, no one believed that Jay-Z, 42, was always so focused on his career that he didn’t take time off to have a personal life. But, it’s almost like he didn’t start dating — although semi-publicly — until after a late songstress’ untimely death and he and his now-wife Beyoncé linked up. Even then, the dating and the wedding were both a big secret.
