Jay-Z (43) was filming a short 24-minute documentary on his 8-show stint that opened Brooklyn's Barclays Center in September. It was released on YouTube and this is a quick highlight. When Jay takes the subway en route to his last show and sits next to a woman named Ellen who has no idea who he is . The ensuing conversation is infinitely sweeter and more humble than if she had. It turns out that the older lady is Ellen Grossman, an artist herself. He could have been a street bum everyone says that they would have had the same conversation, that she is very sweet.
