Leona Lewis' boyfriend Dennis Jauch is reportedly planning to propose her on Christmas this year.
Jauch wanted to buy her lady love a man-made gem for the engagement ring to ease her fears over blood diamonds, Contactmusic reported.
A Source spilled the beans that the performing artist told his pals that he doesn't know where to find a man-made gem.
The 'Bleeding Love' singer and choreographer are dating each other for past four years.
