Taylor Swift & Calvin Harris celebrated their one year anniversary yesterday with a homemade cake. Calvin bought a locket for Taylor with “3-6-2015” engraved in it to commemorate the anniversary. According to a source, Harris wanted to get her something meaningful for the finish of their first year.

“He bought the locket all on his own. Calvin is not a flashy guy when it comes to gifts and he knows Taylor appreciates the small meaningful things, so he thought this would be the perfect gift,” the insider revealed.
