Saif Ali Khan turns 46 today and the actor hosted an intimate dinner at his Bandra residence to bring in his big day. The father-to-be looked dapper in a white jacket as he escorted his mother Sharmila Tagore to his pad. While his wife Kareena Kapoor stayed away from the shutterbugs, her sister Karisma Kapoor was one of the early birds at the party and posed happily for the photogs. But the scene-stealers of the evening were Saif’s children – Ibrahim and Sara Khan.
