The Barfi! star said that she was overwhelmed at the launch event for the single, and commented that she never imagined she would fulfil a long-held dream of her father's to become a professional singer, PTI reports.
"I never thought I would be a professional singer, also I never thought I would become an actor," she said. "If not this then I would be an engineer. I have never sung professionally... I never knew I would be doing it. I can't believe this is my event and I am overwhelmed.
"My father is an incredible singer. I am happy and overwhelmed that my family and friends are here. I am feeling like a newcomer... I am feeling it is my first film."
The actress-turned-singer explained that she had been exposed to all genres of music from an early age but the album will reflect her Indian roots and features a strong Bollywood element.
"I grew up listening to music from my parents. My father used to listen to Mohammed Rafi and my mother used to listen to international music bands like Beatles and Metallica," she said.
"The heart of this album is Indian. It is a desi girl album. We will be shooting the video soon, we are planning things about the album, we will try and add some Bollywood elements to it. I am very nervous, I am shivering a lot."
While Chopra insisted on releasing the song to her Indian fans first, 'In My City' will have its official international launch at the US National Football League pre-game show Thursday Night Kickoff on the NFL network.
"It is an important and huge thing for an Indian to have this launch at NFL. It is a huge honour to have this one-and-half minute version there. No Indian has done that. It is surreal," said Chopra.
The former Miss World added that, while she loves performing, she is not ready to perform live yet.
"I am not prepared for doing live shows. I am very nervous about it. I love performing but when I reach that level I will do live shows. This is just the beginning of my journey in the world of music," she said.
Chopra has collaborated with Grammy Award-winning musician RedOne on her debut album. Single 'In My City' features will.i.am.
