Yes, you are right. There is a considerable age difference between Saif Ali Khan and Amrita Singh. Again there is a huge age difference between Saif and Kareena also. This is sort of a tradition among couples in Bollywood. Amrita Singh is 12 years senior to Saif Ali Khan. Amrita Singh was born on 9th February, 1958 while Saif was born on 16th August, 1970. They had a secret marriage in 1991 when Saif was just 21 years old. On the other hand, Kareena was born on 21st September, 1980. So Kareena is almost 11 years younger to Saif and almost 23 years younger to Amrita.
