Taylor Swift takes not very subtle swipe at Katy Perry

Taylor Swift and Katy Perry's rumoured feud looks set to worsen after the appearance of a surprise guest at one of Swift’s concerts this weekends.

On Saturday in Foxborough, Massachussets, Taylor was performing her hit “Bad Blood”, which is widely believed to have been written about Perry.

One of her dancers popped up behind a glass panel dressed like a shark, in a likely bod to Perry's Super Bowl XLIX mascot Left Shark, causing Swift to laugh mid-song.

Someone's not going to like that...

The latest news comes after Katy Perry waded into the spat between Swift and Nicki Minaj.

Minaj queried the racial undertones behind her snubbed at the MTV Video Music Awards, and Taylor Swift reacted as if she was being called out directly. After a brief spat, Swift apologised appearing to resolve their fight…

…but the spat between her and Perry shows no sign of such reconciliation.
