Kareena Kapoor refuses to act with Ranbir
No doubt that Kareena Kapoor and Ranbir Kapoor will make the greatest pairing in Bollywood but to see them romancing each other is not at all possible since Ranbir Kapoor is the first cousin of Kareena Kapoor.
Bebo said in an interview that Ranbir is a great actor but there is no chance of casting opposite him as they share a brother-sister relationship.
In a new film to be directed by Imtiaz Ali, at first Kareena was decided opposite Ranbir but later Ashtavinayak Productions dropped the idea considering the relationship that they share. But Bebo was not totally dropped from the film, if not Ranbir, she will be paired opposite another heartthrob of Bollywood Imran Khan.
Kareena once expressed her desire to act with Imran Khan.
