Thakur comes from a musical family, as her father is Bengali singer and actor Shakti Thakur and her sister Mehuli Thakur-Goswami is also a professional playback singer.

Thakur got her start by singing in school and college competitions and performing at local functions, and then rose to popularity after placing ninth in Indian Idol 2, the Indian version of Pop Idol. She was never in the Bottom 3 until her elimination, and immediately after she was eliminated, judge Anu Malik offered to help her find a future singing opportunity, which turned out to be a playback song in the movie Jaan-E-Mann.
This led in turn to the opportunity to sing two songs for the hit movie Race in 2008 - "Khwab Dekhe (Sexy lady)" and "Zara Zara Touch Me". She was originally scheduled for only one song, but her first recording impressed the film's directors Abbas and Mustan enough for them to book her a second.
"Zara Zara Touch Me" was enormously successful, becoming the fourth-most-played song on Indian radio during the first half of 2008.
She also sang in the movies Golmaal Returns and the forthcoming Mr. Bhatti on Chutti and Dulha Mil Gaya[6], and is working on her first solo album. As of June 2008, Thakur claimed that the album included a planned nine tracks, of which six had already been written by Thakur and Sachin Gupta, and would be in a blend of rock and classical styles.
She has also sung a song "Khudaya Khair" in the recent film "Billu Barber" starring Shahrukh Khan. She also got nominated for best singer in "Screen Film Awards" for "Zara Zara Touch Me".
