Swift a fan of Shake It Off spoof
Taylor Swift showed she has a sense of humour when she praised a group of frat boys who parodied her video.
The Delta Sigma Phi Beta Mu fraternity at Transylvania University in Kentucky created a comic take on Shake It Off, but, far from being upset, Taylor tweeted a link to their lip-sync video and told them they had "nailed it".
She was so impressed with the video - which sees the boys singing along to the song while dancing through their dorm - that she even invited the group to go and see her perform.
She tweeted: "I'm personally inviting all of these guys (and a date!) to a show on tour next year, it's on me. Nailed it, bros!"
One of the college boys, Daniel Lyvers, shared a picture of the star's tweet on Instagram and wrote: "This is quite simply the best day of my life. #wemadeit."
