Saif was earlier married to Amrita Singh and he has two children with her.
"My relationship with Sara and Ibrahim is the way it should be. It's a strong bonding and we are very good friends," Kareena told IANS.
The 33-year-old, who just celebrated her anniversary with the National Award-winning actor, is bowled over by his good looks.
"Saif is a wonderful actor and he is known for his choice of films. He has never played safe and experimented with everything, and it's great. It's his looks that appeals to me the most," said Kareena.
