Taylor Swift Break Up — Split By Thor’s Hammer

Taylor Swift's big breakup with Tom Hiddleston started to go wrong on the set of the new "Thor" movie — as revealed in the new issue of The National ENQUIRER, on newsstands now! Insiders told The ENQUIRER that Chris Hemsworth was ready to play real-life superhero to save his costar Tom from a villainous romance!

"Chris told Tom that he thinks his relationship with Taylor is toxic," said a source. "He sees her presenting him [with] the same problems as Miley Cyrus did with his brother Liam!"

The celebrity couple had been together for months before Tom finally had to leave to Australia for the filming of "Thor: Ragnarok" — where he'll return as the God of Thunder's evil stepbrother Loki. "Tom spent the summer moaning to Chris that Taylor's controlling, and Chris told him the only way Liam was able to get Miley to shape up was by dumping her!"

"Chris told Tom to do like Liam did if he wants to force Taylor to change her way, and he did," said the insider — with The ENQUIRER first to know, just like when Taylor began secretly romancing Hiddleston!
