"X-Men" showrunner Simon Kinberg debunks speculations that Taylor Swift has been cast as Dazzler for the upcoming film "X-Men: Apocalypse."

Back in July, rumors and speculations surfaced claiming that the "Blank Space" songstress has been cast for the much-awaited "X-Men: Apocalypse" due in theaters in the United States on May 27, 2016.

While it may seem quite unlikely, many outlets jumped onto the bandwagon and even cited that Swift may be the perfect fit to play the mutant named Alison Blaire also known as the Dazzler.

Now, the X-Men's main man has officially revealed the real deal about his favorite songstress getting involved with his latest Marvel venture and explained the entire issue to MTV.

"No, there's nothing to it. I know where [the rumor] came from, because it's my fault," the 42-year-old filmmaker told the outlet while he was promoting "The Martian" at the Toronto International Film Festival.

Kinberg, as it turns out, is a huge Taylor Swift fan and admitted to being so while explaining why he posted a photo over Twitter with the singer and "X-Men: Apocalypse" cast members James McAvoy who plays Professor X and Sophie Turner who would star as the teenage Jean Grey.

"It became for me, it was what I was listening to every morning to get sort of energized and I would listen to it on the set every day for 'Apocalypse'" he explained, describing some of Swift's "1989" album as 'happy-making' and 'the best pop album since Thriller.'

After learning that his favorite lady crooner is due for a concert close to where the Marvel film is shooting some scenes, he did not hesitate to dance the night away together with McAvoy, Turner, Nicholas Hoult and Rose Byrne during the "22" singer's concert.

"So we went to the show, me and those people, and then she invited us to come back and meet her afterwards. It was just a photo backstage at the concert, and that was the only time we ever saw her. That's where that particular rumor came from," he explained, referring to the Tweet below.

While he indeed denied that Taylor Swift would not be appearing in the upcoming X-Men movie, he admitted that he actually thought that it was a wonderful idea to cast Swift as Dazzler but alas, it was not meant to be.

"After I saw those things I was like oh, that's kind of interesting, but no, we were actually just there for her concert," he added.
