Before we start, it is worth noting that Turner is now happily married to Joe Jonas and that this story takes place back in early 2016.
Turner shared her story in a recent interview with Twitter Movies for a feature called 'Behind The Tweets'.
It begins on 26 January 2016 when Sophie made the discovery that Matthew Perry, who played Chandler Bing on the long-running US sitcom Friends, was rehearsing for a new play just around the corner from where she was living at the time.
At the time, Sophie tweeted: "Holy balls. Chanandler Bong himself is rehearsing his play right next to my home."
Chanandler Bong - that's one for the Friends purists out there, for sure.
Sophie explained: "I would walk around the corner every day to go to my local Budgens, which is a great little supermarket,
"And I would walk around the corner every day and I would see Matthew Perry outside smoking a cigarette."
Right, that's step one. Establish where he goes to have a cig. Next step, get his attention.
Sophie devised a plan to buy a lighter from the shop in order to light his cigarette for him. A stroke of genius.

However, as she discovered to her dismay, the cigarette was already lit.
The Dark Phoenix star continued:"I bought a lighter from Budgens so that I could walk up to him and offer to light his cigarette.
"It was already lit, so that was just embarrassing."
She added: "I thought he might see this tweet and then, I don't know, reach out to me and ask me on a date or something.
"But he didn't."
Well, you've got to have a dream, even if it is far-fetched. Everyone's dream should include at least one trip to a Budgens supermarket, as well.

In the full Twitter video, Turner also outlined her love for pop star Zara Larsson, her Game of Thrones co-star and BFF Maisie Williams, and - of course - SpongeBob SquarePants.
She also spoke about recording smells, standing up on the pedals whilst riding a bike, and starring alongside Jessica Chastain in the new X-Men film, Dark Phoenix.
Oh, that's probably why she was there in the first instance, isn't it?
Dark Phoenix is out in cinemas right now.
