Little Women water bottle
Little Women super fan Madelyn Rancourt has gone viral this week.
She posted a TikTok video revealing a big mistake in a pivotal scene in the movie.
Speaking on TikTok Madelyn said, "Alright so I'm a very big fan of Little Women."
"I have the official movie companion book. I have the Louisa May Alcott book with the cast photos and I did see it seven times and with to a Q&A with the cast in New York and saw the film before it came out."
Madelyn then shows viewers a scene from the movie featuring Jo, Amy and Laurie.
And in the background there is a plastic water bottle and a hydro flask.
It's Game Of Thrones with the coffee cup all over again!

Neither the cast or director Greta Gerwig have responded to the blunder.
Water bottle or not, it's still one of our favourite movies of the year!
