Kareena Kapoor is clear she will never endorse food chains like McDonald's or Burger King, known for their beef burgers and the like, while co-actor and boyfriend Saif Ali Khan says he can't think of doing an underwear ad.

"I will not endorse non-vegetarian products like McDonald's or Burger King. I won't endorse alcohol or tobacco. This is the policy I always follow because if I don't relate to such things, I should not advocate them either," said Kareena.

"Endorsing a brand is not only fun but it does add to the bank balance. Apart from that endorsing a good brand helps you in connecting with your fans. Given this, I have to be very choosy about my endorsements because they also help a lot in branding," she added.

Kareena is the face of many leading brands like Kurkure Desi Beats and Vivel soap among others.

Saif, who promotes several brands including Head and Shoulders and Asian Paints, says it is important for him to connect with the brand he endorses.

"For me, brand name is very important. I feel I should represent a brand that I can connect with. This also helps me to reach out to my fans because they can associate with me through that brand. I won't endorse something I don't connect with... like underwear ads. I can do a baniyan (vest) ad, but no chaddis for me.

"It's not the finances always. When a brand approaches us, they do a lot of research before they come to sign us. And when they come to sign, that means you represent something. It also helps visibility," he added.

Saif Ali Khan met Kareena Kapoor for the first time when she was just 14 years old and more than a decade later he fell in love with her. The two are now one of the most talked about couples in tinsel town, but say marriage is not on the cards.

"We do discuss marriage but this is not the right time because Saif is busy in his production house and I am getting very good roles. So marriage can wait," said Kareena.

Saif said, "People say that marriage doesn't affect your career but the fact is it does. Today the whole definition of marriage has changed. We are so well connected, so close that marriage is just a stamp of validation for the society.

"I love her for what she is. We manage to spend a lot of time together and this is the most important factor to make a relationship work."

Kareena also has a legacy of cinema behind her, takes interest in different aspects of filmmaking and might one day go behind the camera like her grandfather and father. But right now Kareena Kapoor says she is happy being an actress.

"I like to know who is going to be the director of photography of my film. How am I going to look. Mostly what happens is when a script is narrated to you, it doesn't turn out to be the same on screen. So an actor has to know all this," said the actress.

When asked would she go behind the camera like her legendary granddad Raj Kapoor and father Randhir Kapoor, she said, "As of now I am getting good roles, so not now. But yeah, I don't rule that out... one day I might direct."
