The 24-year-old country star showed off her new do in an Instagram photo she shared Tuesday morning where she poses next to British singer Ellie Goulding.
"London, I could never thank you enough. See you next time! PS: short hair, don't care. (!!!)" the singer captioned the image.
Before posting the pic, the "All Too Well" crooner shared a video of a group of people watching her get her hair cut. She titled it, "Haircut."
Swift was in London performing her last sold-out concert at the O2 Arena before chopping off her hair Tuesday.
