Rimi Sen was born on September 21, 1981 in Kolkata, India. She is an Indian actress working in the Bollywood film industry

She was first noticed when she auditioned for a Coca-Cola advertisement, impressing Priyadarshan, the director of the ad. Priyadarshan cast her in his hit film Hungama, establishing her in Bollywood.

She then played Amitabh Bachchan's and Hema Malini's granddaughter in the hit film Baghban. Her next big hit was the Yashraj produced Dhoom. Her next releases Phir Hera Pheri and Golmaal have been successful at the box office. Her latest release Dhoom 2, released on November 24, 2006, is another big hit, though she has very little presence in the film.

Rimi is now going by the screen name Rimii. She explains the name change as a career move: there are many other Sens working in Bollywood right now, and a single name may help her stand out from the crowd and stay apart from others.
