Jay-Z's one of the 100 most powerful celebrities in the world but the 43-year-old isn't too big to take the subway - or humbly accept that a passenger might not recognize him.

The moment was caught on camera in Jay-Z's documentary "Where I'm From," which explores the behind-the-scenes work that led to his eight performances at Brooklyn's Barclays Center this fall. The video was posted to Jay's Life + Times YouTube channel on his birthday, December 4.

About 18 minutes into the video, Jay's seen traveling with an entourage en route to his final show. As he descends into a train station, onlookers armed with smartphones tried to grab proof that one of Brooklyn's most famous was riding along with everyone else, including an older woman named Ellen.

She asked if he was famous as he took a seat next to her on the train, to which he replied: "Yes. Not very famous, you don't know me. But I'll get there someday." Catch the rest of their adorable exchange in the video above.

Jay-Z's "99 Problems" has gotten an Election Day remix.

The rapper joined Bruce Springsteen at President Obama's election rally in Columbus, Ohio, on Monday, and at first had a bunch of songs planned, as he told the crowd of about 15,000.

"Then they told me no colorful language, so I brought two songs," he said. "I changed this one up, I have to do it, I'm sorry. I didn't get clearance from the Secret Service, so if they come tackle me on here, y'all can save me."
