Every celebrity knows whoever they follow on Instagram is going to be spotted by eagle-eyed fans and journalists.
So we imagine Katy Perry knew exactly what she was doing when she liked an account named ‘sl****taylorswift’ this week.
Proving the bad blood between the pair is still well and truly flowing she added the account to her list of just 202 people she follows on the photo-sharing site.
But despite what you may think, the page isn’t full of pictures showing Taylor dressed provocatively – not that she ever does anyway.
It’s merely a blonde girl who looks a bit like Taylor who clearly chose the name as a joke and attached a profile picture of the singer seemingly in a old fashioned painting carrying flowers.
John Mayer’s on/off girlfriend could have been getting her own back on the 25-year-old star after she took a pop at her during one of her gigs.
Katy, 30, famously performed with two sharks at last year’s Super Bowl – and the left shark became an Internet sensation after it was spotted getting its dance moves wrong.
As Taylor sang her hit Bad Blood – the song reportedly about her feud with fellow pop star Katy – a shark appeared on stage behind her.
Those in attendance at the show in Foxborough, Massachusetts caught the moment on camera and it was quickly shared online.
In the clip Taylor can be seen giggling as it pops up behind her, while someone in shouts “Argh shark”.
It is thought the shark is one of the dancers that Taylor believes Katy “stole” from her.
