Taylor Swift and Calvin Harris have celebrated one year of dating - and he admitted it was an "easy" 12 months.

The Scottish DJ and the blonde beauty made a special homemade anniversary cake to mark the date they first got together yesterday, and he shared a video online of the New Romantics hitmaker and the calorific treat, which was decorated with "1 year" and red hearts in frosted icing.

In the Snapchat clip, Calvin explained to his fans what the cake was all about as Taylor stood next to him nodding in agreement.

He said: "One year. We got one year cake. We got one year cake. It's one year."


If it wasn't clear what the couple were celebrating, Harris also wrote over the video: "1 year ... that was easy (sic)"

The 26-year-old singing sensation posted a photograph on her Instagram account of a gold locket which had the date they first got together engraved into it.

She added the caption: "3.6.15 One year down! (sic)"

The picture has amassed an incredible 1.1 million likes in the nine hours since she posted it.

Calvin, 32, was clearly in great spirits yesterday as he also posted a picture of Sylvester Stallone looking smug with his thumb in the air on his Twitter account.

The star added the caption: "Mood"

The couple haven't held back in posting their mutual affection for one another online, and Calvin recently gushed over his "beautiful girlfriend" Taylor after she won three Grammy Awards - Album of the Year and Best Pop Vocal Album for 1989 and Best Music Video for Bad Blood.

After the ceremony, which he didn't attend, the DJ shared a picture of the stunner receiving her Best Album prize and wrote: "Congratulations to my beautiful girlfriend."

While things appear to be going swimmingly for the pair on a personal note, he is said to have "politely declined" the chance to collaborate with his significant other.

A source recently said: "Calvin's next single is ready but the label is keen for him to get a big female US star to collaborate on it. They know he attracts amazing names because everyone wants to work with him.

"They floated the idea of him working with Taylor but he politely declined it.

"Calvin has seen how sour things can turn when working with someone he's dating. He is very serious about Taylor and doesn't want to rock the boat. He's smitten."

Calvin previously dated singer Rita Ora but the pair split in June 2014 and she had to scrap several tracks they had worked on together after he blocked her from using the tunes.

He also denied her permission to perform hit I Will Never Let You Down at the Teen Choice Awards because he owns the rights to the song.

Before hooking up with Calvin, Taylor had several other famous failed relationships with the likes of Harry Styles, Jake Gyllenhaal, John Mayer, Joe Jonas and Conor Kennedy.
