Kareena had described Katrina as her would be 'sister- in-law' on the show Koffee With Karan, in reply to a question by its host filmmaker Karan Johar.
This particular episode of the show featured Kareena and Ranbir, who are cousins.
When asked about Kareena's comment, Katrina today said "I don't know...They are cousins...They were pulling each other's leg. It was all said in jest. They were not serious."
"Before the shoot of the episode, Karan had kept a dinner where I and Kareena were there. Kareena said to me she will pull everyone's leg (on the show). She asked me if she can say it (sister-in-law remark) in a fun way...And that was OK with me," the 'Namastey London' actress said.
Ranbir and Katrina, who was once linked with Salman Khan, have always maintained silence over their relationship.
Their rumoured affair once again came to limelight when they were clicked holidaying in Spain a couple of months ago.
