West and his pregnant reality star girlfriend had just landed at the John F. Kennedy International Airport on a flight from Brazil on Tuesday when they were whisked away by an airline greeter.

The employee reportedly let the couple bypass a Transportation Security Administration (TSA) checkpoint to get to another gate quicker, but the stars were later yanked off their connecting flight due to the safety breach and re-screened.

And now the agent is being investigated by the TSA over the alleged violation.

A representative tells TMZ, "An airline employee escorted the two travellers 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 travelers to by-pass the TSA security checkpoint.

"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."

An American Airlines rep says the company is taking responsibility for the incident, according to TMZ. "This was a lapse in judgment by one of our employees," the rep said.

AA adds, "We're working closely with the TSA and speaking to the individuals involved to better understand what happened."
