Pop star Katy Perry expressed her consideration of working with singing ace Taylor Swift if she will apologize to her for her "Bad Blood" behavior.

When a fan asked Perry if she would like to collaborate with Swift in any of future pop projects, she replied as "sure." The star added that she would only consider the option if Swift said sorry to her. The conversation took place on Twitter over the weekend.

The battle between the two superb pop stars can be traced back to a dispute that emerged over the hiring of a dancer who already worked with both the stars. Following the dispute, Swift and Perry once again grabbed focus when they went into a public disagreement when fans started considering Swift's "Bad Blood" as a hit to Perry. According to E Online, Vanity Fair's cover story on Swift vs. Perry feud in September 2015 focused on the incident.

The report claimed that the song revolved around Perry, who has been accused of stealing the touring dancers of the singer a few years ago. Swift, however, never came up to the camera to confirm the speculations. Instead, she seemed to avoid the topic.

According to Hollywood Life, the song from 1989, as Swift described, was a story about her friend who tried to "sabotage" her tour. "I've trusted people before in friendships or relationships and have felt betrayed. I judge people based on their moral code; I think someone is nothing without a moral code. I don't care if you're talented or celebrated or successful or rich or popular, if you have no moral code," Swift was quoted saying on her cover story for Vanity Fair.

"If you will betray your friend, if you will talk about them badly behind their back, if you will try to humiliate them or talk down to them, I have no interest in having a person like that in my life."

Let's wait and watch if Swift apologizes to Perry and helps her in making a spectacular comeback in the industry.
