Kajol is one actress who has a great sense of humour. We have often seen it in her interviews as well. She was recently giving an interview with Shah Rukh Khan when someone played Baby Doll from Ragini MMS and Kajol started singing along. The music stopped but Kajol’s enthusiasm didn’t. The actress continued singing and then began her hilarious “squeaky” voice – yup, just like her character in K3G.
