Left Shark became a Superbowl mascot for Katy Perry, and now it seems Taylor Swift has used the fish to take a jab at the singer while on tour.
Video has surfaced of Swift on stage laughing at a toy shark that appears just as she is singing Bad Blood - a song many believe was written about Swift and Perry's bitter relationship.
The feud reportedly started over the use of backing dancers for the the singer's world tours, with some camps claiming Perry was pinching Swift's best talent. Since then pair have continued to take swipes at each other via social media.
Just last week, Perry dissed Swift for over-reacting to a tweet by Niki Minaj, calling out double standards.
"Finding it ironic to parade the put women against other women argument about as one unmeasurably capitalises on the take down of a woman," Perry said on Twitter.
