Taylor Swift said "I do" to a sweet plan that involved surprising two worthy fans at their wedding in Brant Beach, New Jersey, Saturday.

Max Singer and Kenya Smith's big day became even bigger when the pop star stopped by to pose for pictures, hang out with the happy couple and even serenade them for their first dance.

Yes, Swift sat a piano and performed her hit "Blank Space" for the newlyweds — at what was actually their second wedding.

According to People, Singer and Smith first swapped vows earlier this year — in a hospital room. The couple's earlier ceremony was held to make sure that Singer's mother would have a chance to witness their wedding before she died. Singer even shared a mother-son dance to "Blank Space" at the time, which made Swift's personal performance over the weekend all the more meaningful for the couple.

Of course, Swift knew all about that. Singer's sister had reached out to the hit maker to tell her all about their story and to secretly invite her to wedding No. 2.

Swift's performance wasn't her only gift for the couple — she even hand-painted a special card for them.

Photos from the day prove just how thrilled the bride and groom were to have the unexpected guest show up.
