Svelte Bollywood diva Priyanka Chopra, who packed a punch at the box office with her stellar performance in "Mary Kom" recently, is set to begin work on her new film "Bajirao Mastani". She is full of excitement, but admits she's nervous too.

"Sometimes starting something is so scary n I haven't felt a new beginning for a while. Super excited and totally nervous! Bajirao starts Tom," the National Award winning actress posted on her Twitter page on Tuesday.

A period drama, "Bajirao Mastani", which is filmmaker Sanjay Leela Bhansali's dream project, also stars Ranveer Singh and Deepika Padukone.
