While shooting with the four kids in her forthcoming film 'Thoda Pyaar Thoda Magic', Rani says the atmosphere became very childlike.
'There used to be a lot of goodies to eat on the sets and you can see a bit showing on me too,' said the actress.
'I have put on three kg and the credit goes to Kunal (Kohli). He used to keep telling me that he wanted me to look chubby for the film,' she added.
In the film, Rani plays an angel to four children who are forced to stay with a man they hate and Saif Ali Khan plays the role.
