Looks like Calvin Harris was on to something all along.

After photos surfaced on Wednesday of his ex Taylor Swift looking pretty cozy with her rumored new beau Tom Hiddleston, the DJ decided to purge all of his social media accounts of any remaining photos of Taylor Swift; he even unfollowed her on Twitter and removed his breakup tweet. Even further, he blocked many of her fans.

"He feels like these pictures confirm his suspicions, and it changes everything," the source said. "He is so angry and feels betrayed. He is convinced that Taylor was cheating with Tom while they were still together."

To make the situation even messier, the source also added that Calvin had a wandering eye as well, indicating that they were possibly unhappy towards the end of the relationship and looked for attention elsewhere."They both weren't getting what they needed out of the relationship," the source continued. "Taylor had a feeling he was with other people."
