Juhi Chawla has signed Deepak Tijori's 'Khamosh'. It's a story about a high society escort girl played by Shilpa Shetty. Deepak is maintaining some secrecy about Juhi's role. "She is an old friend and when I narrated the script to her, she was excited to do the movie, because she hasn't done anything like this before. We'll be changing her look for the film. She's the pillar of this venture," he explain.
