Taylor Swift just made one couple's big day even sweeter!
After a fan named Alex Goldschmidt proposed to his boyfriend Ross Girard, the 29-year-old pop star gave a surprise performance at their engagement party.
According to Swift, Goldschmidt had emailed her and told her about his plans to propose. He also mentioned her hit "King of My Heart" was a special one for the duo. So, Swift agreed to attend their engagement party at the Sycamore Tavern in Los Angeles and surprise Goldschmidt's fiancé with a sweet serenade.
Of course, the couple's family and friends were completely shocked to see the 10-time Grammy winner walk out with her guitar.
"I've been off tour for a while, but hopefully it's still all right," she said before performing the number.
Swift performed the song in a blue dress with a white print.
"This is from Alex, but sung by me," she explained to Girard.
Needless to say, the two were truly touched by Swift's sweet gesture.
"I decided to propose to Ross listening to this song in my car," Goldschmidt wrote on Instagram. "I can't thank Taylor enough for wanting to help make this day so special."
