/> Everyone knows by now that Saif Ali Khan wears his love for Kareena on his sleeve. According to friends of both, Saif has never been more committed in a relationship.

Says a close buddy, "There's a kind of fierce and single-minded determination in Saif to make this relationship work for keeps. And it isn't a defiant determination to disprove the cynics who say it won't last.

Saif doesn't give a damn about what people say. He has always gone by his gut feelings, regardless of others' popular. Earlier after Rosa left, there were whispers of Saif being involved with various ladies.

Saif doesn't like the image of the casanova at all. He thinks he's too grown up for it. He wants stability in his life and a relationship that's for keeps. He believes he has found it in Kareena.

Come what may, Saif will make this relationship work."

Marriage is definitely on the cards. Friends say it could happen within a year. In the meanwhile Saif has solemnized his affections for Kareena in an unexpected way.

He has got her name tattooed on his arm.

Admitting for the first time to the permanent love-mark Saif says, "Yes I've tattooed her name. It's on my forearm. And very visible to the world."

Tell Saif he can't back out of the realationship now even if he wanted and he laughs wordlessly.

There's a certainty about his feelings this time. And Kareena is gradually giving in to Saif's persuasive passion.

Earlier when they were together in Bangkok Saif's shooting for Kunal Kohli's film, Saif's co-star Rani Mukherjee was privy to many sessions of Saif's outpourings on his love. Kareena and Saif then brought in the New Year in Hong Kong with Saif's two children. They made a pretty well-adjusted family portrait.

Now shooting in Greece for Yashraj Films' Tashan, Saif and Kareena spend as much time together as possible oblivious to all around, though they don't have too many scenes together in the film.
