20 Celebrity BFFs Who Started Off As Costars

While we're sure that many celebrities have non-celebrity friends, it makes a whole lot of sense that they'd become friends with their fellow famous peers and people they've worked closely with for long periods of time.

Some of them seem like unlikely pairs, others more obvious. But either way, we're here for it. Here are our favorite 15 celebrity BFFs who first met on the set of their shared film or TV show.

Jennifer Aniston and Courtney Cox

The Friends co-stars have proven to be just as close in real life. More than a decade since the show aired its last episode, the pair frequently share selfies together on social media.

Actually, we should mention the entire 'Friends' cast, too.

Maybe one of the reasons behind Friends' success was the fact that all the cast members were friends in real life. Those friendships have spanned decades since the show first premiered and culminated in a reunion special in 2021.

Michelle Williams and Busy Philipps

While Michelle and Busy's friendship first began on the high school set of Dawson's Creek back in 1998, the two have shared a tight bond ever since.

True besties!

Alexis Bledel, America Ferrera, Amber Tamblyn, and Blake Lively

We've all come a long way since The Sisterhood of the Traveling pants, but one thing is still the same: Alexis, America, Amber, and Blake's real-life sisterhood — although, they probably don't all share one pair of jeans anymore.

Shay Mitchell and Ashley Benson.

My teenage self is living for this one.

Shay and Ashley first met on the set of Pretty Little Liars in 2010, and are still very good friends to this day — often sharing adorable TikToks together.

Mindy Kaling and B.J. Novak

Mindy and B.J.'s friendship didn't end with The Office, thankfully. The two have stayed close friends and B.J. is now the godfather of Mindy's two children.

They are two peas!

Hilarie Burton, Sophia Bush, and Bethany Joy Lenz.

Hilarie, Sophia, and Bethany met on the set of the iconic teen drama, One Tree Hill, in 2003, and are now closer friends than ever. The trio made headlines in early 2022 for sharing snaps of their reunion.

Miranda Cosgrove and Jennette McCurdy.

iCarly co-stars Miranda and Jennette's friendship has gone the distance since their Nickelodeon days. These two are still besties, and ironically, take trips to Disney vacations together.

Cameron Diaz and Drew Barrymore.

Cameron and Drew met on the set of Charlie's Angels in 2000, and make up two-thirds of the fierce trio, including Lucy Liu. The pair are just as good of friends today as they were 22 years ago!

Zooey Deschanel and Joseph Gordon-Levitt.

500 Days of Summer, and infinite days of friendship.

Zooey and Joseph met back in 2009, and wowed fans with their on-screen performance. Turns out, that chemistry was entirely authentic! The two hit it off IRL and have been close pals for the last 13 years.

Kate Winslet and Leonardo DiCaprio.

Kate Winslet and Leonardo DiCaprio famously met on the iconic movie set of Titanic. While the world was hoping they might fall in love in real life, they opted for a 26-year friendship instead.

Snoop Dogg and Martha Stewart.

Snoop Dogg and Martha Stewart are an obviously unlikely and peculiar-seeming pair that wound up becoming besties after meeting on the set of Martha and Snoop's Potluck Dinner Party in 2016.

Matthew McConaughey and Woody Harrelson.

Matthew McConaughey and Woody Harrelson undoubtedly share a likeness in their acting performances, and maybe that's why they also click as friends! The two met on the set of True Detective and then again in Surfer, Dude, and have now been pals for more than two decades.

Abbi Jacobson and Ilana Glazer.

Abbi Jacobson and Ilana Glazer met in New York City back in 2007 through the UCB comedy community network before teaming up to create the hit comedy series, Broad City. The two became fast friends and are the very definition of friendship goals.

Snooki and JWoww.

Snooki and JWoww were attached at the hip in Jersey Shore, and were certainly a duo to be reckoned with. Nowadays, the two are still best friends and both living the mom-life.

Will Smith and Alfonso Ribeiro.

Not to make you feel ancient, but Fresh Prince of Bel-Air stars Will Smith and Alfonso Ribeiro are going on 32 years of friendship, and are still as close as ever.

Zach Braff and Donald Faison

The Scrubs actors have been inseparable for the past two decades. They even launched a podcast in 2021 that features them watching episodes of Scrubs and giving fans behind-the-scenes info.

Reese Witherspoon and Nicole Kidman

The two legendary actresses finally got the chance to work together in HBO's hit series, Big Little Lies. Even though they are both powerhouses in the industry, they reportedly hit it off right away becoming fast friends.

Amy Poehler and Nick Offerman

Amy and Nick have actually known each other since the '90s but many fans came to know them through the show Parks and Rec. They have continued to remain friends over the year and even hosted a DIY show called Making It together.

Maisie Williams and Sophie Turner

The two Game of Thrones actresses played sisters on the fantasy drama and in real life, they became close friends. The two even gave themselves the BFF nickname of "Mophie". Aww!
