The whole world knows that Taylor Swift and Katy Perry are enemies due to the constant passive aggressive insults they throw at one another. In Swift’s most recent concert, she could have possibly made another passive attack on Perry.

During Swifts 1989 concert in Foxborough, Mass, Swift had the audience talking when there was a special appearance during her performance of “Bad Blood.”

E! Online reports that one of the backup dancers held up a puppet of a shark while Swift was singing “Bad Blood.”

For those people who don’t know, Perry had her backup dancers dress as sharks during the halftime Super Bowl performance.

One of the sharks used to be a backup dancer for Swift, but left the singer to dance for Perry.

When Swift spotted the puppet during her concert, she let out a laugh and then continued on with her song.

What makes things even more suspicious is the fact that the shark puppet incident happened after Perry got involved in the Swift vs. Nicki Minaj drama on Twitter.

Although Swift neither confirms nor denies if she was taking a jab at Perry, one can assume that it is likely.
