King Khan recently came to co-star Katrina Kaif's rescue after she was almost mobbed at the Mumbai airport

At a recent incident at the Mumbai international airport, Shah Rukh Khan stuck to his popular image of being an actor who is extremely protective about his co-stars.

And this time, he came to the rescue of Katrina Kaif, ex-girlfriend of his archenemy Salman Khan, almost acting like the actress' bodyguard.

Both the actors arrived together in the city after completing the London schedule of their new film.

An eyewitness reveals, " While returning from London, Shah Rukh and Katrina were mobbed at the airport. The media turned up in large numbers to take sound bytes from both the stars.

SRK quickly came forward and shielded her from the crowd, physically keeping people away from her. He kept his arms around the actress and escorted her till her car. He made sure that no one could come close to the actress."

Our eyewitness also adds, "Shah Rukh has a habit of escorting all his leading ladies to their cars at the airport but in this case, he also played Katrina's bodyguard."
