Sridevi is currently celebrating her comeback in Bollywood town through this movie called English Vinglish. She had laughs in Toronto with her director Gauri Shinde during the Toronto Film Festival. these laughs were for the reason that the local media in Toronto believed Sridevi to speak fumbling English like her character in the movie however Sridevi speaks English quite fluently.
Thus this was hilarious for her and at the same time quite difficult to remain in the character. So to maintain and remain in to her character she fumbled while speaking the language.
