Her career was launched by Subhash Ghai who had also launched the careers of popular actresses like Madhuri Dixit and Manisha Koirala. She has been said to have changed her name to Mahima Chaudhary since Subhash Ghai has a superstitious belief of launching big careers with actresses whose names start with the letter ‘M’, but this is not the case, she has kept her real name as she believes that her real name is a very personal part of her and something that she wants to keep. She won rave review for her first performance in Pardes (1997) as a village girl who still values her culture. Unlike most top actress in india. she is the role model in youth in her time. her hot seens makes crazy in mens world.
