Comer, also 26, who has just scooped an Emmy for her role as Villanelle, wrote on Instagram: “World champion right there!!!!!!! We couldn’t be prouder of you Johnson-Thompson.
“Your hard work and dedication shows no limits. Soak it all up. You’re the best… it’s actually official (always has been)! X,” she added, next to a crown emoji.
The pair both attended St Julie’s Catholic High School in Liverpool.
Comer was visibly shocked when she won a best actress Emmy for her role as psychopathic assassin Villanelle in Phoebe Waller-Bridge’s Killing Eve last month.
And Johnson-Thompson congratulated her friend after her Bafta win earlier this year, writing on Twitter: “Unbelievably proud of Jodie Comer. So bloody talented and getting the recognition you deserve!!”
