Pretty soon we should start calling Beyonce and Jay-Z's little one, 'Blanket the Second' in honor of The King of Pop's endearing name he gave is second son.  Lately, we've seen alot of Baby Blue--wrapped up in a BLANKET!  Over the weekend, Blanket II, Beyonce and Jay-Z were spotted having lunch at the trendy restaurant Nobu in the Tribeca area of NYC.  The paps were on hand to snap whatever shots they could get of the family leaving the swanky establishment!  Take a look!
