Rumours of the "Blank Space" singer joining the cast of the ninth installment of "X-Men" film series emerged after Simon Kinberg tweeted a photo of himself with Swift, James McAvoy and Sophie Turner last summer.
According to Swift's representative the casting rumours are entirely "not true", reported Gossip Cop.
The singer was in Montreal at the same time the film was shooting there, but she was in Canada for one of her "1989" concerts, which Simon, James and Sophie attended.
