Katrina Kaif is increasingly becoming a security hazard to herself. In spite of the constant flow of stalkers and mobs, she continues to step out fearlessly, some would say recklessly without care about repercussions.

While Salman Khan has always believed in following security measures, all efforts to convince Katrina to do the same fell on deaf ears. In fact, Katrina has always disregarded security threats.

Some time ago, when hordes of young and old people had descended on her at a public gathering she had fobbed off the security arrangements made by the organizers arguing, "They love me. They can never harm me. "

But her latest daredevilish disregard for all rules of self-preservation takes the cake.

On Monday morning, when Katrina was required to fly to Bangalore for an event with Ranbir Kapoor, Katrina just hopped into a taxi with her hand-luggage and took off. Much to the shock and disbelief of the cabbie who had no clue about the VIP passenger he was carrying until he looked into his rear-view mirror.

While Katrina cracks up at the recollection of the moment when the cabbie spotted her in the rear, her Raajneeti crew were far from amused when they saw Katrina hop out of a cab unaccompanied (even her personal manager and constant companion came straight to the airport). Ranbir and Prakash Jha were seen soundly ticking her off for her disregard for security rules.

Katrina has been indulging in such reckless security-adventures much too often these days. According to a close friend, she takes off on her own, usually accompanied by her trusted driver and no other companion, just for a spin far away to drive off loneliness.

But her latest adventure-ride to the airport on her own, has left Katrina's family in jitters. It has now been decided that Katrina's youngest sister, Isabel, who has been studying cinema in the US, may cut short her acting course to join Katrina in Mumbai.

Katrina admits her family is worried about her safety. "But what's the big deal about hopping into a cab to rush to the airport? Thousands of girls do it all the time. What's there to get hyper?

My driver was late because he got caught in a traffic snarl. If I waited any more I would've missed my flight. So I waved for a cab, hopped in and zipped off. "

What concerns people close to Katrina is her utter obliviousness to obvious security dangers.

Says a close friend, "Katrina doesn't realize the effect that her solitary presence in crowded places can have on people. Hopping into a cab early morning in Mumbai when there are no cops around is just not done. But she refuses to believe anyone would harm her. "

Katrina's family doesn't appreciate her all-izz-well-with-the-world philosophy either. They've taken serious note of her carelessness towards basic protection rules. And, it seems now, her days of zipping off on her own in strangers' company are nearing an end, thanks to the timely intervention of her family.
