Taylor Swift shakes it off, Calvin Harris spins

Taylor Swift and Calvin Harris aren't hiding in separate secluded locations brooding about their recent breakup.

Nah, the two former lovebirds, whose recent split was confirmed Wednesday, were getting on with making their fans happy.

Swift surprised guests at the wedding reception of her fan, Max Singer and his bride, Kenya Smith, in New Jersey on Saturday.

She played a version of Blank Space at the newlyweds' reception in Long Beach Township as guests looked on and sang along, reports the Associated Press, which also said that Swift agreed to attend after getting a letter in April from the groom's sister.

The sister wrote about how the groom was a huge fan and how he and their ailing mother had danced to Swift's song after the couple were married in a hospital room, according to the AP which added that Singer's mother died shortly thereafter.

And while Swift spent Saturday with the couple and guests at the reception, Calvin Harris was returning to work at Wet Republic pool club in Las Vegas.

Several fans as well as the club welcomed Harris back in Instagram posts.
