Jay-Z has joined forces with Bing to promote his new book 'Decoded' and during the cocktail party, he is introduced by Eric Hadley from GM Bing as having 11 debut singles reaching number one, but Jigga was quick to correct the mistake.

When taking to the stage, the 'Empire State of Mind' rapper said, '11 number one albums Eric, not singles." The crowd were quick to laugh and Jay-Z said: "That makes a difference."

Jay-Z hosted the cocktail reception in Miami, where he explained how the partnership with Bing will work.

He said: “It’s almost like I’m trying to simplify the process, almost like a preview of the book. We put all these pages out into the world to be found [and] through Bing search engine you bring it all back together and you can read the book. For participating in it, you get these prizes.”
