Leone and Rannvijay will be hosting the eighth season of Splitsvilla from July 4 on MTV.
Praising Leone, Rannvijay said, "She is very cool, funny, loves to chill. She is by far the nicest person I have worked with. It was amazing working with her."
The actor even felt insecure when his wife got along very well with Leone.
"Sunny and my wife (Priyanka Vohra) have become great friends… They have had dinner together. I was feeling insecure as my wife and Sunny are getting along so well," the MTV Roadies host says.
Rannvijay, who is back on the show after seven long years, is quite thrilled to be part of it again.
"I did the first season that was about two boys from Roadies looking for love. I do believe in love. I think everybody should. This is the only place (show) where you test your limits for love.
"I wanted to be back and the opportunity to work with Sunny was great. I am happy I took this decision. We had lots of fun while shooting this show. Hopefully people will like it," he added.
On the show’s theme, Rannvijay said, "I think they themselves don’t know what they want. Their taste changes quite often. Their choice changes."
"Women want chivalry, humour, respect from partner these are basic things. Besides this they don’t want over protective, possessive man in life. It is a learning curve for me as well," he said.
Leone, said, "I am excited to be back on the show. I want to see what the boys will come up with to woo the women they like. I have had a lot of fun shooting with all these wonderful contestants.
