49ers star George Kittle dishes on Taylor Swift's surprise Nashville performance

Taylor Swift put on quite a show in support of boyfriend Travis Kelce and other NFL tight ends during an appearance in Nashville Tuesday night. 

The popular singer and songwriter stepped on stage at the Brooklyn Bowl for a good cause to perform before a sold-out crowd at the Tight Ends and Friends benefit concert, part of the Tight End University’s (TEU) annual summer training camp.

She performed one song after being introduced on stage by Kane Brown, and, according to one person in attendance, the crowd went wild.
