Later, Chauhan began a romantic relationship with the music composer Hitesh Sonik whom she was friends with, since the days she won Meri Awaz Suno. After dating for more than two years, they married on 24 April 2012, at a low profile wedding ceremony in Mumbai. On 1 January 2018, Chauhan gave birth to a boy.
Sunidhi spoke about motherhood. She stated, “It’s too soon to say how motherhood is treating me. It’s just the beginning and we’re trying to identify each other. I feel like I’m on another planet right now. It’s a beautiful feeling that I cannot explain.”
However, after all that she has achieved, Sunidhi considers it significant to get back to the grind, she reportedly averred, “I plan to go slow for about six months. But work has begun and I could not resist. I will let my baby understand the kind of mother he has. He has to get used to the fact that he will have to travel a lot, and listen to songs…he will get used to it.”
On the work front, Sunidhi is popular for her songs which are touted as item numbers. She has sung songs namely Mehboob Mere, Dhoom Machale, Deedar De, Beedi Jalaile, Sheila Ki Jawani, Kamli to name a few. Talking about it, she said, “Call it item songs or whatever else, I am what I am because of these songs.”
Adding, “However, over the years, things have changed for me. I have sung all kinds of songs. I am glad I didn’t play it safe. I sang a lot of risky songs, and I’m very proud of that. I won’t complain. I’ve got more than I’ve asked for.”
