She says her role on the show is of a detective who unwinds hidden cultural facts about India.
Lisa will travel to Jaipur, Hyderabad, Delhi, Kochi and Chennai and explore the jewellery styles of these cities.
"In the show I play the role of a cultural detective - meaning I get all my natural curiosity answered by experts. I ask and know everything just like a detective about all cultural and traditional richness behind the age-old famous jewellery pieces and also the city, " Lisa dressed in a black off-shoulder dress and decked up in gold jewellery told reporters here.
"Richness of jewellery is embedded in our DNA, in our psyche. I may not be an expert but I am surely a perfect host because I came with minimal knowledge about the show and through the journey, I have learnt quite a lot and I am sure the viewers will also gain ample knowledge from my show."
The 39-year-old feels the show came as a reward to her.
"The whole experience of 'OMG' has been a fulfilling one. When I got the opportunity to be part of this I just couldn't say no. I had got the offer just after six months (of cancer therapy). It came as a blessing, as a reward to me and surely it has got along a lot of excitement and fun back to my life, " she said.
The show is slated to go on air July 11.
