According to at least one online source, one of the most popular singers of this decade could be making an appearance in the new movie. That singer is Taylor Swift and according to the source, the singer was rumored to be preparing for a role in the new film.
Even though fans from both ends were getting more excited with every second while reading about it, the rumor was crushed quickly when Simon Kinberg said that it was not happening. He also said it was his fault when he posted an image of him with the singer and two other actors from the new movie, backstage after a concert.
He made it clear that was the only time he saw Taylor Swift and that there was no reason to believe that she was going to have any role in an X-Men movie now, or in the future. It was just a fun picture taken after a concert and it was posted online.
