Bill de Blasio, Mayor of New York City, has announced Robert De Niro, Alicia Keys, Lady Gaga and John Leguizamo as Mayor's Office of Media and Entertainment (MOME) ambassadors, celebrating the 50th anniversary of the Mayor's Office of Film, Theatre and Broadcasting.

The stars will serve as representatives of New York's media and entertainment industries, promoting the contributions of artists, performers, and professionals to the city's cultural identity and creative economy. De Niro commented 'I grew up in New York - I chose to launch my production company here because there is no better setting than New York for your film, no better city to shoot in than New York. I feel fortunate every time I get to make a movie here'.
