Director Guy Ritchie and his girlfriend JACQUI AINSLEY ensure their chats remain private by speaking to each other in Hebrew.
The Sherlock Holmes moviemaker, who split from Madonna in 2008, started dating Ainsley early last year (10) and the pair now live together at Ritchie's London home.
And they can keep their conversations a secret when they venture out because Ainsley is taking lessons in the ancient language so she can converse with Ritchie, who is already fluent.
She tells Britain's Hello! magazine, "Yes, we can have a secret dialogue together, it comes in very handy! Initially it was difficult as the characters are so vastly dissimilar to English characters and there are two alphabets to contend with. I believe you can learn anything you want if you are determined - one hour a day can go a long way."
