The Hollywood Walk of Fame is home to 2,400 brass stars cemented into 1.7 miles of sidewalk along Hollywood Boulevard. The stars, each recognizing an entertainer of some sort, are visited by 10 million people each year.

Check out a sampling of the celebs who've been immortalized on the Walk of Fame over the years.
