VIDEO : Did Taylor Swift Take a Jab at Katy Perry During Her Concert?

According to E! News, during her 1989 tour stop in Foxborough, Massachusetts over the weekend, Taylor Swift may have taken a jab at Katy Perry while performing "Bad Blood" onstage. After last week's Taylor-Nicki Minaj-Katy Twitter brouhaha, it's clear that there is still mad beef between the two pop stars. During the song, which is allegedly about Katy backstabbing Taylor, a backup dancer held up a stuffed shark puppet, which made Taylor let out a little laugh. And since most people now associate sharks with Katy Perry's Superbowl halftime show social media is buzzing that the moment was a mini diss.
