While on her much-hyped 1989 World Tour, Taylor Swift played a show in Foxborough, Mass. over the weekend. The tour is becoming as well known for its performances as well as its surprise guests, but this show featured a guest no one saw coming: a Shark. While Taylor's dance only appeared in the shark costume for a brief minute, it was undoubtedly a reference to the internet famous Left Shark who famously danced with Katy Perry at last year's SuperBowl and flubbed its dance moves. While the shark sparked laughter from Taylor, it's one more confirmation that the song "Bad Blood" relays to the singer's now-public feud with Katy.
The brief dance performance comes after a week of controversy for the singer who got caught up in a Twitter exchange with Nicki Minaj about the VMAs with Katy Perry seizing the moment to throw some shade at Taylor. While Taylor later apologized to Nicki on Twitter and then spoke to her on the phone, her bad blood with Katy still cleary runs deep.
