Jennifer Aniston's portrayal of Rachel Green in Friends has become somewhat iconic over the years and we can't imagine anyone else in her shoes.
But that's exactly what nearly happened, as it's revealed that Jennifer almost lost out on the part to a Saved By The Bell star.
Instead, the iconic role almost went Tiffani Amber Thiessen who played the role of Kelly Kapowski in the teen series before going on to star in Beverley Hills 90210.
The 44-year-old made the revelation while appearing on Nikki Glaser's Sirius XM show, telling listeners: "Did you know I tested for Friends, for Jennifer Aniston?
"I was just a little too young. I was a little too young to the pairing of the rest of them."
However, she did go on to praise Jennifer's portrayal, adding: "She is very, very funny."
Just when we thought we knew everything about the sit-com, Friends executive producer Kevin S Bright recently made a shocking revelation about Rachel's romance with Joey.
"I can tell you this - in the beginning, Matt LeBlanc did not want to do that story," he told Digital Spy.
"He was very firmly against it, saying that he's Ross' friend, and that the type of friend that Joey is would never go and take someone else's girlfriend."
Kevin went on to explain that it took "a lot of conversations" to convince Matt to get on-board with the storyline, adding that the audience learned to accept it after the initial shock - although we know a few Friends fans who'd disagree with that one.
"I think, if she's not going to be with Ross, who else would you want her with?" he continued.
"That went okay with the audience. No big letters on that one!"
Just when we thought we knew everything there was the know about the series, they surprise us again.
