It’s now up to the couple. They can make it legal any time they want. As far as the couple’s parents are concerned, Kareena and Saif are one compatible couple. And as good as man and wife in terms of parental approval!While Saif is on excellent terms with Kareena’s mum Babita, Kareena is extremely fond of Saif’s kids, Sara and Ibrahim. Says our source, according to Babita, Saif is the perfect son-in-law. She insists that Saif be present at every family occasion, a privilege denied to the earlier men in Bebo’s life. Saif gets along amazingly well with Kareena’s father, sister Karisma Kapoor and brother-in-law Sanjay Kapur. So much is Saif at home with Kareena’s family that his own parents are amused to see him like that.And when it comes to Saifs kids, he says, Kareena doesn’t get to meet them often, but yes, when they do, they are happy to be in each other’s company.Everything aside, it is actually Kareena’s comfort level with Saif's parents that has taken everyone by surprise. Adds our source, there was discernible and unconcealed lack of chemistry between ex-wife Amrita Singh and his mother. They hardly ever met. And things just got worse when he dated Rosa Catalano, whom Sharmila Tagore openly disapproved of.Kareena, on the other hand, has thoroughly endeared herself to Sharmila and Saif’s entire family. Incidentally, our source says, when she was dating Shahid Kapur, Kareena succeeded in winning over his father Pankaj Kapur and Pankaj’s second wife, Supriya Pathak. But yes, Shahid’s mother Neelima Azim disliked Kareena and the feeling was mutual.But with Saif and Kareena together, it’s a completely different story. Both the Khans and the Kapoors share a warm camaraderie. The signal is coming on strong and clear, Kareena is totally welcome to wed the scion of the Pataudi khaandaan . .
