The 32-year-old actress, who tied the knot with actor Saif Ali Khan in October last year, says she has friends outside Bollywood and she tries to keep her personal life separate from her work.
"The key is to realise that we are here to work in this industry. I'm not over-friendly with anyone, I don't get into anyone's personal space because I don't want people to get into mine. I have a life outside of films," Kareena told PTI.
Having faced huge media curiosity surrounding her marriage to Saif, Kareena says she prefers her work to make more news than her personal life.
"Some of my friends are from the industry but most of them are not. So that is a part of life that I cherish. I go to work and come back. I want to keep it like that - go to work, come home and let my work talk more than anything else," she says.
Post marriage the actress has been super busy shooting for brand endorsements while Saif has been shooting for Bullet Raja.
"Saif has been shooting for Bullet Raja and I have shot for Dabangg 2 song and promoted Talaash. I have also shot for eight brands since the wedding. We actors sign up brands then we forget that we have to give them four days each to shoot. I have been shooting every day. Work is my passion and Saif respects that," says Kareena.
Kareena, who did Dabangg 2 item number Fevicol for "good friend" Salman Khan, says she shares a warm relationship with the actor since the days her elder sister Karisma used to work with him.
"Salman and Karisma go back 12-16 years, they started with movies like Nishchay (1992) and I used to be on the sets. I was 8 or 9 years old then. He has that kind of love for me, as Karisma's younger sister. He was friendly during 'Bodyguard' and he respects the kind of person that I am. You can see the warmth between us and that's what I love."
Salman's father, veteran scriptwriter Salim Khan had specially called Kareena to praise her performance as Rosie in her latest release Talaash.
"When a living legend like Salim saab, who has written such great films and characters, calls you, it's something else. In my decade long career, no one has given me the compliment that he has for Talaash.
"He never called me after Jab We Met. He said I have been studying your work, I think you are one of the best that we have, so please continue doing such roles. That's a great compliment."
Ending the year with an Aamir-Khan starrer film, Kareena is set to begin 2013 with his nephew Imran Khan as well as Prakash Jha's Satyagraha.
"I ended the year with Aamir, I'm going to start the year with Imran. Life's always a full circle, I've got to work with both. In January I start shooting for a film with Imran Khan and then I have Satyagraha with Ajay Devgn. We start shooting for that on February 1."
