As we have seen this year, Jay Z has had quite a relationship with Brooklyn's Barclays Center. This could change in the near future -- as far as the financial aspect is concerned. As Forbes points out Jay Z is selling his share due to his sports agency, Roc Nation Sports.

Forbes estimates that Jay Z could get $1.5 million for the sale of his Barclays shares.
