Taylor Swift fans were in hysterics when one fan was convinced that they spotted a Hollywood actor on-stage at The Eras Tour earlier this month.
Taking to the stage in Houston, Texas for the second night in a row, amid her three day run at the NRG stadium, Taylor, 33, performed a string of her greatest hits last night (April 22) in front of a sold-out audience.
But some fans were distracted by an unearthed comment a Swiftie made under a livestream from a show that took place earlier on in the month.
Each night, Swifties attending the tour will livestream the concert on social media for fans around the world to tune in to.
And on April 6 at the Arlington show, someone livestreamed the gig online, which sparked a hilarious comment from one fan.
The comment came during Taylor's Midnight set, which sees her croon the best-loved tracks from her latest album.
Dressed in a midnight blue bodysuit with a matching garter, Taylor sultrily danced with a chair in front of her while her backing dancers followed suit.
With her dance troop behind her, fans were quick to "spot" a famous face throwing some shapes behind the global megastar.
Fans were commenting on the livestream at the time, with one person making a hilarious comment, leaving thousands of Swifties in hysterics.
"What is Timothée Chalamet doing?" asked one confused fan on the livestream, which naturally made its way onto TikTok (amassing more than 450,000 likes), and then Twitter.
The person who the fan believed was Timothée, was actually one of Taylor's back-up dancers - Sam McWilliams.
One fan ended up posting a screengrab of the TikTok - which was of the livestream and hilarious comment - on Twitter, which left fans going wild.
Sharing it and writing "Oh that's not-" the post garnered more than 900 retweets and around 17,000 likes, with many quick to comment on the post in sheer disbelief.
"That isn't Timothée??" asked one fan, who clearly thought it was him.
Another quickly commented that the dancer did look "similar" to the actor, while a third person said: "Now I can't unsee it!"
A fourth person then added: "Screamingggg!"
While a fifth said: "He's serving."
This comes as Taylor continues the US leg of her The Eras Tour, which sees the hitmaker perform a jampacked setlist of tracks from all of her beloved eras.
The Anti-Hero singer's US leg of The Eras Tour will come to an end in the summer, with the country-turned-pop-singer still yet to announce UK and international tour dates.
