Katy Perry has told the world that she is open to working with Taylor Swift, if she apologises, sources stated.

The 31 year old tweeted that she’s willing to collaborate if Taylor apologises for their ‘reported feud’.

“If she says sorry, sure!” Perry wrote in response to a fan asking, “Will you collab with Taylor Swift?”

Perry’s conflict with Swift began in 2014 when Swift hinted to Rolling Stone that her song “Bad Blood” is about a fellow singer. Swift claimed the unnamed person nearly destroyed a headlining tour, reportedly.

Social media users speculated Swift was talking about Perry, who tweeted, “Watch out for the Regina George in sheep’s clothing,” a day after the interview was published.
