While their characters Ross and Rachel were involved in a high-profile love story, fans may not have known the actors who played them actually had a crush on each other at one point.
We can’t believe this is the first we’re hearing of this.
“The first season I had a major crush on Jen,” Schwimmer revealed.
“And I think we both, at some point, were crushing hard on each other but it was like two ships passing because one of us was always in a relationship and we never crossed that boundary. We respected that.”
Aniston agreed and confirmed their first kiss came on screen when Ross and Rachel embraced at the Central Perk coffee house in season 2, episode 7.
She said: “So we just channelled all of our adoration and love for each other into Ross and Rachel.”
What could have been, eh?
Casting for the show was a nightmare
Although the casting choices seemed perfect for the show, Marta Kauffman and her co-creators David Crane and Kevin S. Bright went through a lot to get the right people.
“We saw approximately a gazillion people!” said Kauffman.
Schwimmer had quit TV but they begged him to join the show and sent gift baskets. They must have been some pretty nice gift baskets.
Both Perry and Aniston faced an obstacle too, with both of them already signed to other shows.
Aniston asked to be released and that show’s producer told her that Friends would “never make her a star”. The joke is definitely on them.
LeBlanc was up against one other actor - who funnily enough returned in one episode as Fake Joey. The actor– who had just $11 in his pocket at his audition – also turned up to the audition with scab on his nose from a drunken mishap with a toilet.
Matt LeBlanc dislocated his shoulder during filming

Season three’s The One Where No One’s Ready is best known for the moment Joey enters the room wearing all of Chandler’s clothes in an argument over a chair.
But during the special it was revealed the episode also resulted in an injury for one of the cast members.
LeBlanc was required to jump onto the furniture as part of the script.
The first three attempts went “perfectly,” producers said, but the fourth resulted in LeBlanc dislocating his shoulder.
Talk about commitment to the role.
The incident was shown during the special.
Funnily enough, this happened when LeBlanc missed the traditional huddle before filming. We’re not superstitious, but it is strange coincidence...
Phoebe and Lady Gaga perform a duet
The star-studded special saw one of the world’s biggest pop singers performing alongside a cast member.
Kudrow, in character as Phoebe Buffay, was seated on the Central Perk sofa, guitar in hand, for a rendition of her famous song Smelly Cat.
She was soon joined by Lady Gaga for a duet, before later being accompanied by gospel singers.
“Still think it’s better when it’s just me,” Kudrow muttered.
We all know from the show that Phoebe is definitely more of a solo artist.
At the end of Friends, Monica and Chandler, happily married and having started a family, were moving out of New York City to embark on the next stage of their lives together.
However, that was not the original plan.
Producers revealed the “insane” reaction of the studio audience when it was first revealed Monica and Chandler had spent the night together convinced them to pursue the storyline, rather than leave it a one-off.
Kaufman said: “It was such a powerful moment that we knew we had to explore it more.”
Can you imagine what would’ve happened if the audience had a different reaction?
