Earlier today, Turner took to social media to give her gal pal a low-key shout out to honor a very special day, August 7, 2009, a day that changed their lives eight years ago today.
Posting an adorable photo of the pair wearing matching Halloween costumes (in which they appear to have dressed up as naughty Brownies), the redhead captioned her Instagram post, "Happy 7th August my soulm8 @maisie_williams."
In return, Williams posted photos of the friends and wrote on her Insta, "Happy 7th August."
So what's so special about August 7, 2009?
