Calvin Harris Reacts to Taylor Swift and Tom Hiddleston: 'She's Doing Her Thing'

Calvin Harris really seems to be enjoying the bachelor life.

Following a rambunctious "leg day" on Wednesday that included shirtless selfies and rants while in traffic, a new photo of Harris posing in a bright blue Speedo with his friends surfaced. The underwear model's pal, Emil Nava, posted the pic earlier this week with the caption: "We said YES."

The 32-year-old DJ also appeared to make amends with his ex-girlfriend, Taylor Swift, when he started re-following her on Instagram on Wednesday, after deleting all images last week of the "Out of the Woods" singer on social, following news that she was dating Tom Hiddleston.

Harris also reportedly decided to re-follow another ex-girlfriend, Rita Ora, on Thursday, and she returned the favor by re-following him.

The musician's social media shakeup has now been trumped by his over-the-top promotion of the release of his and Dizzee Rascal new song, "Hype," on Friday. Given how much Harris has been socialing about the track, it's certainly appropriately titled.

Prior to the song's release, the "This Is What You Came For" artist seemed to get surprisingly candid in his Instagram comments, allegedly sharing his thoughts on the end of his high-profile relationship with Swift. "[Taylor] controlled the media and this situation," Harris appeared to argue on one of the many comments. "I had no idea what was going on. So that kind of makes it a lot worse from my perspective."
