The singer turned up for selection on Monday morning in Nashville, Tennessee, to be vetted by the court for an aggravated rape and kidnapping case.
A fellow potential juror, Tracey Bates broke the news when she tweeted: "I am on jury duty with @taylorswift13."
The singer was in a holding area at the courtroom with dozens of others waiting to hear if they would be selected.
Initially it seems people weren`t allowed to take pictures but the singer did go on to pose for several selfies while waiting.
A number of pictures were posted on social media but have since been deleted or made private.
As it turns out Taylor Swift won`t actually be serving on the jury. There was a conflict of interest because of an ongoing sexual assault case she is involved in in Denver, Colorado.
The Davidson County district judge agreed to dismiss her because she did not feel she could be impartial.
Speaking to the Guardian, Ken Whitehouse, a spokesman for the Davidson County district attorney general`s office, said: "She asked to be left off out of concern for an upcoming trial in Denver where she was - she used the term - `groped` by a fan at a meet-and-greet."
Swift had not been nominated for an award at this year`s MTV Video Music Awards but many thought her absence was down to her long-running feud with Kanye West and his wife, Kim Kardashian West.
Kanye West had been given four minutes on stage with which to do whatever he wanted.
He did briefly mention Taylor Swift.
