Sharma first started her career with modelling, she is also the brand ambassador of Olay in India.

Sharma caught the eye of producer Aditya Chopra, and he signed her on his next directorial venture titled Mohabbatein. The film also marked the launch of five other newcomers, Uday Chopra, Jugal Hansraj, Jimmy Shergill, Shamita Shetty and Preeti Jhangiani. Mohabbatein also starred superstars Amitabh Bachchan,Shah Rukh Khan and Aishwarya Rai Bachchan. It was a huge hit and started Kim's career in Bollywood.

Her seven years in the industry have been disappointing, as she has not had a hit since Mohabbatein.
