Trust Taylor Swift to shake off a breakup like the best of them.
After PEOPLE exclusively broke the news of the singer’s recent split from her DJ and producer boyfriend, Calvin Harris, 32, Swift put her focus elsewhere and lifted the spirits of some very special fans just days later.
After her surprise appearance over the weekend at Max Singer and Kenya Smith’s New Jersey wedding, Swift, 26, was photographed Tuesday leaving a gym in New York with a smile on her face.
A guest at Singer’s wedding opened up exclusively to PEOPLE about Swift’s sweet gesture. “There were lots of emotions entering [the wedding],” says the guest.
“Of course there was sadness as well, and Taylor was able to really transform that sadness into a celebration.”
A longtime fan of the star, Singer and his late mother shared a mother-son dance to Swift’s hit “Blank Space” at his first wedding ceremony in the hospital before she died.
Swift surprised the newlyweds at their second wedding celebration on June 4 with an acoustic version of the song after Singer’s sister Ali reached out via a fan letter in April.
Posing for selfies and goofing off with the bridal party and guests, “everyone at the wedding was blown away by the magic she was able to create,” says the guest.
“We could never have dreamed that she would have responded to the letter in the way that she did. Taylor was unbelievably down-to-earth and normal.”
