Teenage climate change activist Greta Thunberg has changed her name to Sharon on Twitter after a clip of Amanda Henderson on Celebrity Mastermind went viral.
The Casualty actress gave Greta an entirely new name when asked by host John Humphrys to identify the Swedish teenager while she sat in the famous black chair.
Humphrys asked the actress: “The 2019 book entitled no one is too small to make a difference is a collection of speeches made by a Swedish Climate change activist. What’s her name?”
Unable to pick up the clues, Henderson simply replied: “Sharon.”
Greta has now responded to the mix-up, which left Celebrity Mastermind viewers in stitches, by changing her name to Sharon on Twitter.
The episode of Celebrity Mastermind saw Henderson joined by Paul Chuckle, Geoff Norcott and chef Levi Roots on the show.
After the actress mixed up the name social media users quickly flooded the site with their reactions to the comical answer.
One tweeted: “Oh this is just gold. SOLID GOLD!”
“Omg everyone knows Sharon gave up climate activism years ago,” added another.
A third said: “We can skip straight to 2021. This year won't get better than this.”
Greta became one of the most-talked-about people of 2019, after gaining international recognition for her campaigns to raise awareness for climate change.
Amanda Henderson is best known for playing Robyn Miller in Casualty.
She also made a brief appearance in the latest film adaptation of Les Misérables.
