An industry source told NDTV that event organisers the Moranis are planning a series of shows with the actress.
"After hits like The Dirty Picture and Kahaani, she's become a huge star and even overseas her fan following has increased manifold. So the logistics of a series of shows with Vidya as the star performer are being worked out.
"Most of these shows will be in Europe and America, and are scheduled to kick-start this October," explained the source.
The Moranis will also be enlisting a popular music composer to go on the world tour with Balan, with Mohammed Morani saying: "Talks are on for a music composer to be a part of these shows. Vidya is a major star today with back-to-back super-hits. And along with a music composer, we can package a nice entertaining show.
"We have done shows with a top actress and a music composer before - Karisma Kapoor and Adnan Sami. Those had been big hits then."
However, he went on: "It's still in the planning stages. Vidya found it a great idea and is very enthusiastic about it. However, we can't confirm anything now as things are still in the pipeline."
