Here are 10+ co-stars who became best friends (and those who didn't).

We can never get enough of their adorable friendship, which started on the set of Friends.

“We just have fun, we laugh, we're inseparable, and it's great," Cox told TV Week. Courteney was even Jen's maid of honor in her wedding to Justin Theroux!

2. Enemies: Blake Lively and Leigton Meester

If you've never seen photographs of these two outside of Gossip Girl, there's a reason for that.

"Blake and Leighton have never been best friends, and never professed to be," Blake's rep once wrote. "Blake goes to work, does her job, and goes home."

3. Besties: Cameron Diaz and Drew Barrymore

While the pair knew each other before Charlie's Angels, it was that filming experience that really cemented their friendship.

Drew called Cameron the most loyal friend. “Not that any one of us are going to jail anytime soon, but 100% she’d get in there and get you out," she told Good Housekeeping.

4. Enemies: Debra Messing and Megan Mullally

They played best friends on Will and Grace for eight seasons and even returned for the show's revival. But rumors has it that these two can't stand each other.

In the midst of these rumors, the pair even unfollowed each other on Instagram.

While on her podcast, Mullally brought up being bullied at her workplace.

Many believed she was referring to Messing.

"I've been bullied — I'm 60 and I'm being bullied right now, so you know it's a very insidious and dangerous thing and I never want to lose that happy and innocent part of myself but it's almost like you have to kill that," she said.

5. Besties: Sophie Turner and Maisie Williams

These two are basically sisters, just like they portrayed on HBO's Game of Thrones.

It was even Sophie who convinced Maisie to take her latest role in The New Mutants. "It’s so wonderful having Sophie as a friend and a voice of reason," Maisie told Grazia Daily.

6. Enemies: Alex Pettyfer and Channing Tatum

It was Alex came out and said that Channing doesn't like him — and that it was his own fault.

He told The Hollywood Reporter that since he was nervous on set, it made him come off as standoffish and arrogant.

Things really hit a breaking point when he rented an apartment that was owned by Tatum's friend.

But since the place apparently had terrible mold and dust, Alex left.

He then forgot to pay four months of back rent since his cousin died. This resulted in an angry email from Channing.

7. Besties: Leonardo DiCaprio and Kate Winslet

Despite their insane chemistry, these Titanic co-stars never pursued a romantic relationship. They did, however, become BFFs!

She even refused to boycott the Oscars in 2016 since she was so sure Leo would win. "[H]e is my closest friend in the world and I just couldn't imagine not being there to support him," she told Vanity Fair.

8. Enemies: William Shatner and George Takei

Their feud has been going on for five decades! In his 1994 autobiography, George wrote that his Star Trek co-star would pretend not to know him on set.

This led George to not invite Shatner to his 2008 wedding.

9. Besties: James Franco and Seth Rogen

These two have been a wacky duo ever since they starred in Freaks and Geeks together. From there, they've done a number of movies together.

Now, as adults, they drink wine together and renovate and decorate each other's houses. Vanessa was even in Ashley's wedding!

12. Enemies: Lucy Liu and Bill Murray

13. Besties: Brad Pitt and George Clooney
