Paris Hilton briefly found herself involved in another incident at an airport before being cleared for takeoff.
“Scary that it got on plane,” she wrote.
A few minutes later the socialite reported security had finished sweeping the plane and she was set to board again.
According to TMZ, law enforcement sources said the flight's eagle-eyed passenger had found a “box-cutting knife” that belonged to a member of the airline crew.
Airline officials knew whose knife it was and did not contact police, the gossip site reported.
The incident marks the third time this year that Hilton has experienced unusual travel glitches at an airport.
In September, Hilton was denied entry to Japan when her flight landed at Tokyo’s Narita airport.
Back in July, Hilton was reportedly breifly held by police on the French island of Corsica upon arrival. She was released without charges.
