One man pulled off the surprise of a lifetime this weekend when, unbeknownst to his friends, family and fiance, he brought out none other than Taylor Swift for a special acoustic performance at their engagement party.

He had previously reached out to the Grammy winning vocalist via email and asked her to help them celebrate their big day, explaining that her song “King of My Heart” held special significance for the couple. Happy to oblige, Swift appeared at the gathering, acoustic guitar in hand, and serenaded them with the Reputation track.

“I’ve been off tour for a while, but hopefully it’s still alright,” she said, mentioning her fifth concert trek that spanned from May to November of last year. “This is from Alex. It’s sung by me, but it’s from Alex.” After the performance, Swift posed for a picture with the couple. See the touching clip below.
