Toronto, Sep 14 (IANS): "X-Men: Apocalypse" writer Simon Kinberg has shot down rumours that Taylor Swift would make a cameo appearance as mutant Dazzler in the upcoming film.

"No, there's nothing to it. I know where (the rumours) came from, because it's my fault," Kinberg said while promoting "The Martian" at the Toronto International Film Festival here.

The rumours had emerged when Kinberg was photographed with the "Bad Blood" singer alongside other cast members such as James McAvoy and Sophie Turner, reports aceshowbiz.com.

"...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.

When Swift's tour came to Montreal, where "X Men: Apocalypse" was being filmed, Kinberg, McAvoy, Turner, Nicholas Hoult and Rose Byrne were excited and they didn't want to miss the concert.

However, Kinberg admitted that he actually loved the idea of Swift appearing in the film.

"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 said.

Michael Fassbender, Hugh Jackman, Jennifer Lawrence, Olivia Munn, Oscar Isaac and Alexandra Shipp are other actors in the cast.

Taking place a decade after "Men: Days of Future Past", the movie will be released in US on May 27, 2016.
