Keith Olbermann: The news pundit is a graduate of Hackley School in Tarrytown.
One of Keith Olbermann's teachers at Hackley said he would "wind up either in politics or influencing it." His teacher was right: He went on to work as a sports broadcaster for ESPN and a news commentator for MSNBC and Current TV.
Jimmy Fallon: The comedian and talk show host graduated from Saugerties High School.
Jimmy Fallon's eighth-grade yearbook said he was "Most Likely to Take Over for David Letterman." After a successful stint on "Saturday Night Live," he now hosts NBC's "Late Night with Jimmy Fallon," which airs in the same time slot as Letterman's former NBC talk show.
Liza Minnelli got her first taste of stardom when she starred in Scarsdale High School's production of "The Diary of Anne Frank" in 1961. She went on to achieve the rare distinction of an "EGOT" – which means winning an Emmy, Grammy, Oscar and Tony Award.
Dick Clark: The television icon graduated from A. B. Davis High School in Mount Vernon.
Dick Clark was named "The Man Most Likely to Sell the Brooklyn Bridge" while he was attending A.B. Davis High. Although he wasn't able to achieve that feat, he did go on to become a TV icon as the host of "American Bandstand," "Dick Clark's New Year's Rockin' Eve" and "The "$100,000 Pyramid."
Stanley Tucci: The Oscar-nominated actor is a graduate of John Jay High School in Cross River.
Stanley Tucci stayed connected to the Hudson Valley long after he graduated from John Jay High. Besides collaborating with high school classmate Campbell Scott on four films, he attended Purchase College, where he gave his roommate Ving Rhames the nickname “Ving.” In recent years he has called North Salem home.
Nicole "Snooki" Polizzi: The reality star attended Marlboro High School in Marlboro.
Nicole Polizzi earned her nickname when she was in the eighth grade; her friends named her after a character in the 2001 movie "Save the Last Dance." Her cutesy nickname and brash attitude helped the Marlboro native achieve superstardom on "Jersey Shore."
Sean "Diddy" Combs: The rap mogul was raised in Mount Vernon and attended Mount St. Michael Academy in the Bronx.
Although he attended school in the Bronx, Diddy grew up in Mount Vernon. He credits the late Heavy D, a fellow Mount Vernon native, as "the person who made me who I am today." Diddy went on to become one of the most successful figures in the music industry, due to his work with a variety of pop stars, including Yonkers native Mary J. Blige.
In the caption underneath her high school yearbook photo, Vanessa Williams wrote, "I?ll see you on Broadway." She fulfilled her promise, going on to star in the Broadway musicals "Kiss of the Spider Woman," "Into the Woods" and "Sondheim on Sondheim." She also has had success in music, film and television.
Donald Trump: The celebrity millionaire is a graduate of the New York Military Academy in Cornwall-on-Hudson.
Donald Trump excelled in sports while attending New York Military Academy, and was even inducted into the school's Sports Hall of Fame in 2005. "The Apprentice" host has been less successful when it comes to movies: He won a Razzie Award for worst supporting actor for his cameo in the 1990 comedy, "Ghosts Can't Do It."
Despite getting kicked out of Roosevelt High for drug use, and eight separate stints in rehab throughout his career, Steven Tyler is still rocking. In 2012, he left his gig as an "American Idol" judge to continue making music with his band Aerosmith.
