It seems there really is ‘Bad Blood’ between Katy Perry and Taylor Swift, with the ‘Dark Horse’ hitmaker weighing in on Tay’s recent Twitter beef with Nicki Minaj.

As we previously reported, Her Minajesty and T-Swizzle clashed on the social-networking site after the rapper expressed her upset that ‘Anaconda’ wasn’t nominated for the Video of the Year gong at the 2'015 MTV VMAs.'

After a number of tweets trying to justifying why her promo should have received a nod, she then wrote: “If your video celebrates women with very slim bodies, you will be nominated for vid of the year.”

This really ticked off T-Swizzle, who responded: “I've done nothing but love & support you. It's unlike you to pit women against each other. Maybe one of the men took your slot…”

Nicki was clearly surprised by Tay’s tweet, with the ‘Blank Space’ singer later inviting her on stage if she does win the accolade for ‘Bad Blood’.

While many thought the feud had cooled, Swifty’s rumoured enemy Katy Perry has now stuck her two cents in.

Appearing to throw shade at T-Swizzle, Perry wrote: “Finding it ironic to parade the pit women against other women argument about as one unmeasurably capitalizes on the take down of a woman…”

She then added that her pal Rihanna is really the one who’s missed out at the VMAs, stating: “The real travesty is where is the shine for #BBHMMVideo when VMA eligibility period was 7/7/14-7/1/15 & that gem dropped 7/1... @MTV.”

It’s no secret that Taylor and K-Pez aren’t BFFs, with the ‘Shake It Off’ star appearing to reference their feud during an interview with' Rolling Stone' last September.

Meow, it seems the claws are well and truly out this time...
