Bollywood director Karan Johar has said that it is unfair to compare Kareena Kapoor to Alia Bhatt.

The 42-year-old who has worked with Kareena in 'Kabhi Kushi Kabhi Gham' and launched Bhatt in 'Student of the Year' said: "There is only one Kareena Kapoor. I am not only a huge fan of her work but I value her as a friend. Kareena and Alia are two different people.”
