Taylor Swift was performing at London's O2 Arena on Saturday, February 1 when a fan decided to rush the stage.
The unknown man managed to climb all the way onto the stage, eventually dashing up to Swift at the top of a staircase.
Though she seemed a bit shaken at first, Swift handled the situation incredibly well by shaking the man's hand before security approached. He was rather swiftly removed from the stage. (Sorry, couldn't miss that perfect pun opportunity.)
