It's only been two months since we first learned (via a "candid" coupled-up photo) that Taylor Swift and Tom Hiddleston are dating.
But as her relationships so often do, the Swiddleston romance is proceeding rapidly.
In fact, over the weekend there was talk of Swift and Hiddleston getting engaged.
Now, however, it seems the couple may have rushed right past the wedding rumor phase and skipped straight to the breakup.
Or at least that's the conclusion some fans have arrived at following a week during which Swift and Hiddleston spent an awful lot of time apart.
We guess that's to be expected in a relationship made up of two very in-demand people who hail from different countries, but all the alone time Taylor and Tom have been getting the past few days has raised eyebrows on social media.
Two details in particular have Swift obsessives wondering if she and Hiddleston have called it quits.
First, there was Hiddleston's return to Australia for work purposes.
Witnesses who spotted the actor at the airport say he was sporting a lot of luggage - almost as though he didn't want to leave anything at Taylor's place.
On top of that, Tom missed a major social event in Taylor's life.
Swift's BFF Karlie Kloss turned 24 last week, and Taylor attended her birthday celebration solo.
Could this mean that he and Hiddleston are no longer an item?
Tough to say, but they're no longer spending every second by one another's side.
So at the very least, the honeymoon phase is over.
Like we said, relationships move fast in Taylor's world.
