Clay Aiken was involved in an airplane disturbance with a female passenger on Saturday while on the way to Tulsa International Airport.

Concertgoers who attended the former “American Idol” singer’s Saturday evening concert at Tulsa’s Brady Center said afterward that Aiken joked on-stage about being beaten up by a girl earlier in the day.

FBI Special Agent Gary Johnson said there was a dispute between a male passenger and a woman on the flight but could not confirm the passenger was Aiken. He said the dispute was over the male passenger’s foot resting on the woman’s armrest. He said there was an allegation the woman gave the male passenger a “minor shove” during the argument.

“At that point the flight crew was able to resolve the situation,” Gary continued. No injuries were reported and no arrests were made.
