Socialite Kim Kardashian came under fire from her Twitter.com followers on Tuesday after she nearly disclosed the identity of an undercover U.S. air marshal while on board a flight bound for Los Angeles.

The Keeping Up With The Kardashians star logged on to the website after boarding a plane in New York and told fans she was seated next to a top secret agent - whose identity is concealed to ensure the safety of fellow passengers.

She wrote: "I'm on the airplane...love wifi. I am sitting next to an Air Marshall (sic)! Jim the air marshal (sic) makes me feel safe!" Kardashian's 'tweet' sparked fury among some of her followers, who raised concerns about the star exposing such privileged information.

However, Kardashian brushed off the criticism and defended her air companion, whose full name was not revealed.

She responded: "RELAX I just told u guys the Air Marshall (sic) is sitting next to me, highly doubt anyone is twittering like me on this flight! Shhh. Air Marshall's (sic) are supposed to keep their identity concealed. He did! I am just a private eye & assumed, so I asked him & he was honest!"
