We may have some "Bad Blood" in the water.

Taylor Swift's 1989 World Tour stop in Foxborough, Massachusetts over the weekend featured a cameo from a life-sized anthropomorphized shark mascot, that some believed to be a dig at "Left Shark," Katy Perry's Super Bowl dancer-turned Internet meme. Judge for yourself:

The performance comes after Katy tweeted out during Taylor's twitter exchange with Nicki Minaj last week, "Finding it ironic to parade the pit women against other women argument about as one unmeasurably capitalizes on the take down of a woman..."

Many of Katy's fans believe the shark shade is real.

Meanwhile, we're all just wondering if this quarrel will ever end!
