Dominic Monaghan's Lost Love is Getting Serious  5/20/05

Lord of the Rings star Dominic Monaghan's burgeoning romance with his "Lost" co-star Evangeline Lilly appears to be getting serious.

The British actor and Canadian beauty were romantically linked back in January (05) when they attended the Golden Globes together and were "inseparable" all night.

Friends claim Monaghan is so loved up he's actually thinking about marrying the former missionary and model.

A source says the star recently told him, "I can't believe how lucky I am - here I am on this fantastic television show, filming in Hawaii and going out with the most beautiful girl in the world."
