British-Indian model cum actress Karishma Kotak became a house hold name after her participation in the drama spinning reality show 'Bigg Boss' season 6. Hosted by Bollywood superstar Salman Khan, the show brought Karishma into the limelight for her beauty and it was reported that soon she would enter Bollywood.

It was rumored that Salman was taking keen interest in a budding actress' career and was all set to mentor her. And all these rumors have turned to be true as we now hear that the actress has been finalized to lead Sohail Khan's upcoming film 'Mental' which was earlier titled as 'Radhe'.

Diana Penty who made her debut with 'Cocktail' was one of the top contenders for the role but it was apparently on Salman's insistence that Karishma got the film. The project is expected to go on floors by February 15, 2013.
