Taylor Swift Sings 'King of My Heart' for Newly Engaged Fans! (Video)

This sounds like the best surprise ever for a Taylor Swift fan!

The 29-year-old singer helped her friend and fan Alex Goldschmidt surprise his new fiance with a special performance at their engagement party on Saturday afternoon (February 23) at Sycamore Tavern in Los Angeles.

“There is one secret that I didn’t trust any of you with. There was a person who is not here who sort of played a part in all of this. So I would like to welcome my friend Taylor,” Alex said while surprising everyone with the special guest.

“So Alex emailed me and said that he was going to do this and that there was a song that was very special to you two called ‘King of My Heart.’ I’ve been off tour for a while, but hopefully it’s alright. This is from Alex, but sung by me,” Taylor said before singing the song.

“I decided to propose to Ross listening to this song in my car. ❤️ I can’t thank Taylor enough for wanting to help make this day so special,” Alex captioned the video.

Congrats to the happy couple on their engagement!
