Actors from the CBS Original series Blue Bloods, Tom Selleck, Donnie Wahlberg, Len Cariou, Vanessa Ray and Marisa Ramirez, visited the "World's Most Famous Building" to honor the last season of the show in partnership with CBS and the DEA Widows' and Children's Funds. During the lighting ceremony, the cast flipped the world-famous light switch, lighting the building blue for the night. They then posed for pictures throughout the Observatory Experience, including the 2nd Floor Exhibit, and the 86th and 102nd Floor Observatories.
