The British star was clicked passing by a graffiti of Swift, hinting at their sudden break up, reported E! online.
The art with a message directed at the "Thor" star showed the singer talking on the phone with a speech bubble that read, "Oh Tom...I love you too...But...".
The artwork, created by artist Fussy Human, seemingly depicted the moment Swift, 26, broke up with Hiddleston, 35, following their whirlwind romance.
The pair's romance was confirmed in June of this year after they were photographed canoodling in Rhode Island. They ended up calling it quits in September.
