Sunidhi Chauhan's life looks a lot like that of the princess locked in the pages of a fairy tale. Born On 14th August 1984.She crooned her first number Ladki Diwani (Shastra) in 1994, went on to win the mega final of Meri Awaaz Suno in 1996, has sung for over 2000 Hindi and regional language songs till date.On the personal front she is married to director Bobby Khan (he has directed music videos for Anamika and Daler Mehndi)On march 31,2002,and walked out of marriage in september 2003 . It has been a long journey from New Delhi to Mumbai for the artiste who began crooning at the age of four.

"Tabassumji noticed my ability and asked me to come to Mumbai, where I met Kalyanji Bhai. My real name is Nidhi Chauhan, but he felt that Sonali and Sadhana were lucky and changed my name to Sunidhi," she recollects.

Sunidhi Chauhan shot to fame after she sang 'Zindagi' in Ram Gopal Verma's Mast. Sandeep Chowta's first film got her ideal young voice in Sunidhi and her song became the most memorable number for that film. She has sold her solo album called Aira Gaira Nathu Khaira.
She was the recipient to the RD Burman award for most promising newcomer in the year 2001.

She started her singing career at a very early age of four. She participated in many competitions and made her presence felt. Her family soon shifted to Mumbai when Tabassum, a TV host spotted her talent and expressed to her parents that she could further her career if they went to Mumbai. She became quite famous through the various competitions she participated in. Her performances were telecast all over India through the National Television channel Doordarshan, through the music show "Meri Aawaz Suno" where she won the "Lata Mangeshkar Trophy" for the best female singer of India along with Pradip Somasundaran in the male category. This was the first such televised contest in India in 1996. Her first break in a Hindi film was in the film Shastra followed by Gang, Veergati, Dahek, Bade Dilwala, Raja Ki Aayegi Baraat, Shyam Benegal's Samar and Vidhu Vinod Chopra film Mission Kashmir. She had no formal training before she entered into various national singing competitions. Lata Mangeshkar offered to train her when she won on the nationally-telecast "Meri Aawaz Suno"

Her singing career got a big boost when Sandeep Chowta gave her the first major break in "Mast". After "Mast" there was no turning back. Sunidhi Chauhan had been receiving criticism for a mature voice despite being young. However this criticism ended once Chameli came with her biggest song to date "Bhaage Re Mann" and today she is known as the most versatile singer after Asha Bhosle.
