The US Transportation Security Administration (TSA) is investigating a security breach involving celebrities Kim Kardashian and Kanye West at JFK airport, New York City. The two celebrities were allowed through major checkpoints without any security screening, but later were taken off the airplane for additional screening, which delayed the flight by nearly an hour.

According to reports, an excited airline employee took the two celebrities past the major checkpoints at the airport without going through security protocol. A TSA spokesperson said that the two were escorted by the airline employee through a non-public area in order to provide expedited access to their domestic flight. “In doing so, the airline employee violated security protocols by permitting the travellers to bypass the TSA security checkpoint.” Bypassing of security checkpoints entirely is not permitted.

The agency statement continued: “TSA officials learned of the violation and conducted a private screening of the two passengers in the area of the jetway. The passengers were cleared to board their flight, which departed after a delay of approximately 50 minutes. TSA is actively investigating the incident.”

Kim, who is a reality star, is expecting her first child with boyfriend West in July, and was flying home with the rapper after a trip to Rio de Janeiro, Brazil, where they enjoyed the city’s annual Carnival celebration.
