Taylor Swift and Calvin Harris have removed all traces of their 15-month relationship from social media and word is he now suspects his "Shake It Off" girlfriend may have strayed before they officially called it quits.

All Harris' suspicions have come to the forefront after Swift was recently spotted making out with British actor Tom Hiddleston just weeks after she and Harris publicly confirmed their split.

Sources tell TMZ, Harris believed the two were in a "committed relationship," but sometime in early May came to suspect something might be amiss.

After their split became official, Harris shared on social media that the two still had "a huge amount of love and respect for one another," but since the pics of Swift canoodling with Hiddleston surfaced he has deleted the tweet from his profile.

Rumors are Harris is now "pissed and feels betrayed" by Swift's speedy rebound. She and Hiddleston were first publicly spotted together on May 2, dancing at the Met Gala, a month before she and Harris went public with their split.

In an apparent case of art coming to imitate life, Swift recently morphed into a "psycho serial-dater girl" in the video "Blank Space." In recent times, she has been romantically linked with John Mayer, Harry Styles, Conor Kennedy, Zac Efron, Eddie Redmayne, Jake Gyllenhaal, Cory Monteith, Taylor Lautner, Lucas Till and Joe Jonas, all of whom she's rumored to have written songs about.
