Is there bad blood now between Taylor Swift and boyfriend Tom Hiddleston?

The couple had their first “major argument,” according to Us Weekly, and Hiddleston's busy schedule might be to blame. According to a source close to Swift, the two fought over not being able to find time to see each other face-to-face.

“There was so much going on so it was hard making their schedules work,” the source reportedly said. “And they were upset they couldn't see each other.”

The report comes a week after Hiddleston was spotted boarding Swift's private plane. The “Thor: Ragnarok” actor reportedly jetted off to see his lady love in her seven-bedroom Rhode Island home. Hiddleston stayed for a couple of days before returning to work in Australia.

However, while their busy schedules have been affecting their relationship, the two are staying strong, according to the source.

Despite getting spotted packing on PDA several times, the two have remained quite cryptic about their relationship. Hiddleston has hinted at the relationship, although he did not openly address it.

During a Facebook Live Q&A with The Hollywood Reporter, the actor said, addressing a question about his romance with the “Shake It Off” singer: “We all live in a world where every phone has a camera and there's nothing new, really, about the spotlight to me. I think that's what happens when you're a public figure.”

Their relationship has, indeed, been one that the public loves to feast on. When photos of the two surfaced online, many were shocked. Some even went so far as to shame Swift for pursuing a new relationship right after her breakup with DJ Calvin Harris.

Speculations about the two started swirling when they were spotted dancing at a MET Gala after-party in May. They were first seen together in public in June, according to Billboard.
