It’s well-known at this stage that TayTay has been causing a lot of Bad Blood in the celeb world. The recent news that Hiddleswift is no more has also provoked a lot of people to put a big question mark over the singer's head.

In the latest development, Katy Perry said she’s willing to end her long-running feud with Taylor Swift on one condition.

During a recent Twitter Q&A, a fan asked: ‘Will you collab with Taylor Swift?’

Katy responded with the following:

 

In the past, Taylor accused Katy of stealing three dancers from her RED tour in 2012. However, Katy now seems to be saying the Shake It Off singer should apologise to her. Katy also backed Calvin Harris in a Twitter ‘rant’ against Swift, again suggesting that there’s more to this feud than meets the eye.
