Global pop sensation Taylor Swift, who has been involved in a romantic relationship with Kansas City Chiefs tight end Travis Kelce for nearly a year, has been targeted in what appears to be a terrorist plot against one of her concerts.

According to a report from the Associated Press this week, two suspected extremists were arrested in Austria on Wednesday as one of them appeared to be planning an attack against a Taylor Swift concert in Vienna, Austria.

Franz Ruf, the public security director at Austria’s interior ministry, said that authorities were aware of “preparatory actions” for a possible attack, indicating “that there is a focus by the 19-year-old perpetrator on the Taylor Swift concerts in Vienna,” the Austria Press Agency reported this week.

Ruf said that the 19-year-old who was planning the attack had pledged an oath of allegiance to the Islamic State group, commonly known as ISIS. He also said that chemical substances were secured and were being evaluated, but didn’t give more details.

Swift is slated to perform at Ernst Happel Stadium in Vienna, Austria on Thursday, Friday and Saturday as part of her Eras Tour. Even though the suspect has been apprehended, security measures for the concerts will be stepped up as a result of the threat.
