Amrita was born to well-to-do Chitrapur Saraswat Brahmin family. She speaks English, Hindi, Marathi, and Konkani.. Her dad’s name is Deepak Rao. She stands about 5′5″ feet tall. She attended Cannosa Convent Girls High School in Mahim, Mumbai. For College, Rao went to Ruparel College, where she was a Psychology student, but later quit college in order to pursue a career in modelling. Amrita also has a twin sister named Preeta Rao.
She entered the world of modeling quite by chance, when she auditioned for an advertising film for Fairever Face Cream. She was selected for the film, and since then appeared in a number of television spots for several products. She has recently been signed on as the brand ambassador for Miss Players.
She made her cinematic debut in the 2002 film Ab Ke Baras, but gained recognition only after the success of her 2003 film, Ishq Vishk, in which her portrayal as Payal earned her the girl-next door image. Success followed for her in 2004 films like Masti and Main Hoon Na. However her following releases Deewaar (2004), Vaah! Life Ho To Aisi (2005), Shikhar (2005), and Pyare Mohan (2006) did poorly at the box office. Her most recent release, Vivah opposite Shahid Kapoor was a universal success. Her performance was well appreciated from critics. Next, she is doing Athidhi with Telugu movie star Mahesh Babu.
