Calvin Harris and Taylor Swift’s separation reportedly did not involve a third party, however, a recent report suggests that this may not be true.

Sources have shared with TMZ that Harris had his suspicions that “something was up” with former girlfriend Swift several weeks prior the couple’s separation. The DJ and pop singer called it quits in early June after nearly one year of dating. Sources revealed that Swift’s former beau had his doubts in early May, although at that time, Harris and the pop singer were still in a “committed relationship.”

Harris suspicions were said to have been “confirmed” when photos of the “Bad Blood” crooner and Tom Hiddleston kissing on a beach surfaced, as stated in the same report. The images also captured the two celebrities sharing a few sweet moments together while watching the ocean. Avid fans may recall that Swift and the “Thor” actor danced together at the Met Gala held on May 2.

Sources also told TMZ that Swift’s former boyfriend “feels betrayed by her” and that “he’s pissed” at the situation. The DJ even recently deleted a message he previously posted on Twitter at the time of the former Hollywood couple’s break-up where he wrote that there was still “a huge amount of love and respect,” as stated in the same report.

Harris has also unfollowed Swift on social media following the release of the singer’s photos with Hiddleston, according to Us Weekly magazine. He was said to have also blocked off some of Swift’s fan accounts. Twitter fan account TSwift News took to the said social media site on Wednesday, June 16, to share that Harris has blocked the said account. “Calvin blocked me and I didn't even tweet him anything mean … OKAY BRO,” TSwift News wrote.

Apart from unfollowing Swift and blocking some of the singer’s fan accounts, Harris reportedly posted a message on Twitter that he has now deleted after photos of his former girlfriend kissing the “Avengers” star were released, as stated in the same report. Harris’ now deleted Tweet contained the message, “Oh boy it’s about to go down.”

Meanwhile, Swift and Hiddleston have yet to confirm or deny their new relationship status.
