Sunny, who recently hosted MTV's "Haunted Weekends" made inroads into the Mumbai entertainment industry following her 2011 appearance on "Bigg Boss Season 5".
"I recently hosted a show for MTV and I totally loved working with such a creative bunch of people. So when they came back to me with the offer of hosting 'MTV Splitsvilla', I immediately said yes," Sunny said in a statement.
"It's a fun show focusing on the youth and one of the biggest and most watched shows on MTV. I'm excited to be a part of 'MTV Splitsvilla' and I hope people will love me in my new avatar as well," she added.
The show has an equal number of girls and boys fighting their battle of love to win the crown of the king and the queen.
Sunny will co-host the seventh season of the show with Nikhil Chinapa. It will go on air in a few months, said a source.
The actress has been successful in creating space and visibility for herself on the Bollywood screens so far. After her debut with 2012 erotic thriller Jism 2, she featured in Jackpot and Ragini MMS 2. She has also grooved to an item song in "Shootout At Wadala".
The last season of MTV Splitsvilla was hosted by Sherlyn Chopra.
