Actor Karan Mehra is planning to sue Sushmita Sen's brother Rajeev Sen for linking him with his wife Charu Asopa. "What romance is Rajeev talking about? I had spoken to Charu for a while at a promotional event in June. After that, we never connected until today. Prior to the event in question, I had met Charu about 10 years ago," says Mehra in an interview with Times Of India.
