Reese Witherspoon was mistaken for the singer Carrie Underwood by a fan, in an error that seemingly delighted the two stars.
"To the woman in the parking lot who just asked me if I was Carrie Underwood: You officially made my day!" Witherspoon tweeted.
Underwood was quick to reply to the post with: "YOUR day?!?!?!?! That lady just made my whole life!"
Noha Hamid, the fan who mistook Witherspoon for Underwood, then posted a TikTok video explaining Witherspoon had been wearing "a big cowboy hat, kind of a mask”, making it tricky to tell who she was.
She said when she approached Witherspoon, the actor said: “Hey, oh no, I'm not Carrie Underwood, but have a great day!”
Hamid only realised it was Witherspoon later on.
Witherspoon was last seen in Little Fires Everywhere alongside Kerry Washington. The Independent’s critic Ed Cumming awarded the show four stars.
