Beyoncé made a quick cameo Friday night on new hubby, Jay-Z's, at NYC's The Heart of the City concert. With rumors confirmed that the newlyweds are expecting, should Mrs. Z be shaking that hard? It might damage the baby. And in prepping of the media frenzy that will ensue once Beyonce starts showing, I'm taking it upon myself to dub this power couple "JayonZé."
