The pair haven’t been photographed together for over a month, with their schedules reportedly forcing them to spend too much time apart.
Hiddleston, 35, is currently in Australia filming Thor: Ragnarok.
Reports of disagreements between the couple have also surfaced, with Taylor believed to be uncomfortable with the level of publicity their relationship garnered.
"Tom wanted the relationship to be more public than she was comfortable with," reports Us Weekly.
"Taylor knew the backlash that comes with public displays of affection but Tom didn't listen to her concerns when she brought them up."
