Tina Fey and Amy Poehler
Twenty-five years ago, Tina Fey and Amy Poehler met in Chicago at the ImprovOlympic, thanks to their mutual friend, theater co-founder Charna Halpern. The pair instantly clicked and quickly became the best of friends, later working together on the hit sketch comedy series "Saturday Night Live." Over the years, as both women have explored other professional ventures, including producing and writing, they've continued to support one another, often appearing in each other's projects.
Matt Damon and Ben Affleck
The friendship between actors Matt Damon and Ben Affleck is the stuff bromances are made of. First meeting in 1981 when Matt was 10 and Ben was just 8, the boys from Cambridge, Massachusetts, went on to work together in Hollywood, earning their first Oscars together as screenwriters for their hit 1997 film "Good Will Hunting." Even throughout the many changes in their careers and personal lives, these two have remained loyal friends.
Will Smith and DJ Jazzy Jeff
Meeting in 1985 at a party, DJ Jazzy Jeff and up-and-coming rapper Will Smith developed a fast friendship that led to the formation of their hip-hop group, DJ Jazzy Jeff & The Fresh Prince. The friends released their debut album, "Rock the House," in '87 and would go on to release four more albums before Will's acting career took off. Although Will doesn't make much music these days, Jeff has worked on all of his solo music projects as well. The two remain close friends to this day.
Drew Barrymore and Cameron Diaz
Actresses and BFFs Drew Barrymore and Cameron Diaz first clicked while filming their 2000 action-adventure movie "Charlie's Angels" and have remained tightly connected ever since. In 2018, Drew, who currently stars on the Netflix original series "Santa Clarita Diet," told ET Online that her relationship with Cameron was "more than best friends," saying they were more like sisters who "push each other" and are "very honest with one another."
Dean Martin, Sammy Davis Jr. and Frank Sinatra
Three of the members of The Rat Pack: Dean Martin, Sammy Davis Jr. and Frank Sinatra, were also close friends throughout their lives. Along with fellow members Joey Bishop and Peter Lawford, the trio performed in sold-out Las Vegas shows and on the big screen in films like "Ocean's 11" and "Robin and the 7 Hoods." During the civil rights movement, Frank even went so far as to skip performances where African-Americans were banned.
Ben Stiller and Owen Wilson
Ben Stiller and Owen Wilson are members of the "Frat Pack," but this dynamic duo alone has been in 13 movies together. The Frat Pack was a name given to a group of comedians that starred in multiple films together in various combinations. The friendship and working relationship between Ben Stiller and Owen Wilson began in the 1990s. Before they had worked together, Stiller actually reached out to Wilson after having seen his work to let him know that he was a fan.
