British pop star Leona Lewis is learning to speak German for the sake of her boyfriend Dennis Jauch. The Bleeding Love hitmaker has been dating the German actor/choreographer on and off since last year (12), and she has now revealed she is trying to master his native language. Jauch has even purchased language learning software to help the singer, but Lewis admits she is still struggling to get to grips with German. She tells Britian's OK magazine, "I'm really c**p! He tries to teach me but I'm so rubbish. He got me a (language learning software) Rosetta Stone pack but it's still really hard."
