Before Taylor's squad we all looked to these two as the ultimate Hollywood BFFs.
Matt Damon and Ben Affleck have been friends since they were eight and ten years old.
That's a feat for any adult human, let alone two guys navigating celebrity life.
In the ultimate 'Aw' moment of the week, Ben Affleck took to Instagram today to show his love for his long-time buddy.
In celebration of National Best Friend's Day (June 8), Ben shared a sweet throwback photo of his bestie.
We're waiting on the full story of what went down here, but, needless to say Ben ended up with his face in a cake.
The caption simply read: "This guy".
Matt and Ben grew up around the corner from each other as kids and eventually went to the same high school. Despite being in different grades, they still hung out and worked together as cinema ushers in the summer holidays.
They later went to college (Matt went to Harvard, while Ben dropped out), and eventually penned the film Oscar-winning film Good Will Hunting while living in a Los Angeles apartment in their mid-20s.
Fast forward nearly 20 years since they won their first Academy Award and the pair are still going strong. Aw, you guys!
