Calvin Harris called out Taylor Swift on Wednesday after the singer's rep confirmed bubbling rumors that she actually wrote the lyrics to Harris' hit "This Is What You Came For" under a Swedish pseudonym. After confirming the rumors himself by responding to a tweet by People magazine -- and calling Swift an "amazing lyric writer" in the process -- Harris didn't mince words when it came to Swift's recent shenanigans.

I wrote the music, produced the song, arranged it and cut the vocals though," he said. "And initially she wanted it kept secret, hence the pseudonym."

Taylor and Calvin hugged each other tight at this year's iHeartRadio Music Awards, in April. She evenhave him a sweet shout-out during her speech.

Taylor and Calvin continued their anniversary celebrations with a Snapchat video that features a festive cake calling out their relationship milestone.

At May's Billboard Music Awards in Vegas,Taylor and Calvin took their relationship to the next level, sitting beside each other for their first official event together. Both musicians took home awards, and each time Taylor won, Calvin gave her a big hug, at one point giving her a kiss on the cheek.

The cute couple kicked off Summer 2015 together, floating on an inflatable swan in a ridiculously cute picture that Taylor captioned, "Swan goals."

The pair walked hand in hand beside Ed Sheeran when the group had a lunch date together in NYC in late May.

In June, the couple had a double date with Gigi Hadid and Joe Jonas (aka "GI Joe") — plus fifth wheel Karlie Kloss.

Calvin Harris kicked off the Fourth of July weekend with a sweet snap of Taylor at the barbecue. He captioned it with, "She cooks too [fire emoji] [fire emoji] [fire emoji]."

Taylor and Calvin were spotted holding hands in April, both of them sporting coordinating leather jackets and Taylor wearing a big smile on her face.

OK, so Calvin may not be pictured, but it was sweet when Taylor cheered and danced throughout Calvin's show during KIIS FM's Wango Tango concert in LA in early May.

The couple took their romance on the road in late April, when they were spotted riding in a car and laughing together in LA.

It was awfully adorable when Calvin posted a picture of Taylor's cats on Instagram the night they cohosted a BBQ at her house in LA in April. (He obviously knows the way to her heart.)

In June 2015, Taylor shared Gigi Hadid's Instagram post , calling Gigi, Calvin, and Karlie Kloss "her favorite people."She wrote , "I took a photo of my favorite people — they were laughing so hard, the lens couldn't capture it fast enough."

Taylor got a piggyback ride from Calvin during her big Fourth of July weekend with friends.
