?BEIJING, Aug. 6 (Xinhuanet) -- American singer Taylor Swift suffered unexpected attack by a crazy male fan during her "1989 World Tour" stop in Canada, revealed media reports on Thursday.

Taylor Swift is one of the most popular singers in the world, and her new album "1989" got blockbusting.

It happened at Taylor’s tour stop in Edmonton Alberta. As she performed her song "Bad Blood", a male fan somehow got out from the audience, onto the stage, and grabbed Taylor's ankle.

The 26-year-old singer apparently was shocked by this act and looked visibly shaken. But she managed to carry on with performance like a professional.

She wisely strutted back down the catwalk as her security guards presumably took matters into their own hands.
