Celina, 32, a leading voice for the rights of the LGBT community in India, has crooned Lata Mangeshkar's upbeat number 'Uthe Sabke Qadam' from 1979 romantic comedy 'Baton Baton Mein'. It has been reworked by Neeraj Sridhar of Bombay Vikings.
"This is the first ever United Nations endeavour for a Bollywood styled campaign. It was for a cause. I have sung and starred in the video and it is a beautiful story for LGBT issues," Celina told PTI i an interview.
The official launch of her song will take place on April 30 in Mumbai, after which it would also be available on the Radio.
The former Miss India, who was on a sabbatical after welcoming twins Winston and Viraaj with husband Peter Haag in 2012, says music has always held a special place in her life.
"Singing has been a part of my life since I was a little girl. I come from a family where music and singing has been a very integral part. My aunts are masters in music," she said.
