So Taylor swift showed up to my cousins wedding... 😳 #Surprised
Back in 2016, Taylor surprised two fans, Max Singer and Kenya Smith, at their New Jersey wedding. Apparently the groom's sister had reached out to Taylor to inform her of the wedding and let her know that Max and his mom used to dance to "Blank Space" frequently in the hospital before his mom died. Much to the crowd's delight, Taylor sat down at the piano and began singing "Blank Space" at the reception.
