Hiddleswift were inseparable at the start of their relationship, but things are said to have cooled down dramatically with the couple supposedly entering "crisis mode".
Taylor Swift and Tom Hiddleston have previously flaunted their love around the globe and even sported matching 'I [love] T.S and T.H' t-shirts.
And of course, they met each other's parents, but Night Manager star Tom is said to have put his foot down.
"Tom can't deal with being a laughing stock and has told Taylor he's done unless there's a 360-degree change on her part," a source told Radar Online.
"It's become a total charade and Tom is sick of being treated like a glorified escort."
Tom wants to prove that their relationship isn't a joke.
"Tom is just done with it," an insider also told the website.
According to Us Weekly, the pair recently had a blazing row, which started because their hectic work schedules meant they weren't seeing each other.
"They weren't spending as much time together lately. Ir was hard making their schedules work."
Tom, 35, is currently in Australia working on Thor: Ragnarok, and the distance has become tough.
Despite the speculation, the pair have the Emmy Awards coming up next month, which would be a perfect opportunity to shun any relationship troubles.
Tom is nominated for his role in The Night Manager.
"Tom normally doesn't like his public life overlapping with his private life but he is so happy with Taylor that it's the perfect time," a source told The Sun .
"The Emmys red carpet itself would give them the most publicity, and organisers have made it clear to Tom and his reps that she is more than welcome to join him."
Will she or won't she?
