Tennis star Sania voted Hyderabad as her Love Capital because "I've lived there all my life", while actor Ayushmann has picked two cities - Delhi and Chandigarh.
The movement, by Snapdeal.com, aims to get votes from people across the country for the city they associate with love.
"My Love Capital is an endeavour by us to bring back positivity and love for our country, its cities and the people around us," Kunal Bahl, co-founder and CEO, Snapdeal.com, said in a statement.
"The measure of success in this movement is not which city emerges as the Love Capital of India, but whether it galvanises people to feel more positive about the country we live in. We are hopeful and confident, that in our own small way, we'll be able to move the needle," he added.
The voting began Monday, and the results of the poll will be announced Feb 13, a day before Valentine's Day.
A dedicated online destination with presence on social networking sites like Facebook and Twitter will act as the platform for the movement, where anyone would be able to vote, upload photographs and videos denoting the city they associate with love the most.
