Taylor Swift and Selena Gomez are reportedly working on a diss track for the latter’s ex-boyfriend Justin Bieber. With his latest song “What Do You Mean” making rounds online, the the Disney alum allegedly wanted to release a new song following “The Heart Wants What It Wants” to share her side of the story.

Several media outlets claim that Selena Gomez is done writing passive aggressive songs about Justin Bieber. It was said that she is asking help from Taylor Swift to write the perfect song that will sum up how she feels.

"Not only is Taylor Swift basically the Queen of break-up songs and revenge songs, but she also despises Selena's ex-boyfriend Justin Bieber - so Taylor is more than happy to lend a hand," reported Celeb Dirty Laundry.

The publication stated that Selena and Justin actually got back together early this year. Their relationship, however, soon ended when he found out that the "Good for You" singer is hanging out with Orlando Bloom behind his back. It did not help that Justin was often spotted with supermodel Kendall Jenner.

Although the release date of the new Selena Gomez and Taylor Swift song has yet to be confirmed, the outlet claimed that the new track is going to bring in more money for both singers. It was said that it could surpass the success of her most recent collaboration with Zedd titled "I Want You to Know."

"At this point, all Selena and Justin's feud is doing is making them millions of dollars richer. Both revenge songs are set to be a huge success, and Selena's will be a force to be reckoned with if Taylor Swift accompanies her on the vocals. They can even do another 'Bad Blood' themed music video and some celebrity guests to help them throw some shade at Biebs," the site reported.
