The filmmaker says he didn't feel it was right to approach Kareena for the lead role in the upcoming film as she is expecting her first child but he would like to rope her for a small appearance.
"It would have been easy to call her and tell her to do the film. She would have said, 'Let's do it'. But I can't do that (referring to her pregnancy). I will miss her for sure," Rohit told PTI.
The fourth movie will go on floors next January and hit theatres during Diwali.
Kareena featured in the second film "Golmaal Returns" and the third part "Golmaal 3" of the Ajay Devgn-starrer franchise.
It was in July this year, when Kareena's actor husband Saif Alif Khan confirmed that his 35-year-old wife is pregnant. The baby is due in December.
