THE OFFICE star Lucy Davis is fighting to save her two-year Hollwood marriage, we can reveal.

And the beauty is so worried about losing actor Owain Yeoman she seems to have piled back on all the weight she LOST after their wedding.

Troy star Owain has even been spending nights away from their home and staying in his old bachelor flat.

Meanwhile the 35-year -old daughter of comic Jasper Carrott-who shed THREE STONE when she moved to LA with her husband in search of film roles-looks a picture of misery as she trudges home clutching cakes after a trip to the shops.

Unhappy

And a pal disclosed: "Lucy and Owain have been rowing all the time mainly because his career has really started to take off so he has been away from home a lot filming.

"Right now she is a bit down and her weight has gone up. Everyone is hoping they can get things back on track."

"Owain's family were out visiting recently and witnessed how much strain their marriage is under and how unhappy Lucy is. They said she was just not herself and seemed vacant and sad.

"Both their families are doing what they can and trying to be a tower of strength to both of them."

Lucy has seen her own career soar with roles in TV hits like Ugly Betty and Californication since she quit Britain for Hollywood after finding success as the popular Dawn Tinsley in The Office.

The blonde has always had to battle with her weight-but after her marriage she slimmed down from size 14 to 8 and landed Hollywood roles.

Lucy said at the time: "I wish I could be one of those people who is indifferent about their weight, but since I've lost weight I've had three roles-so that has to tell you something."

Just last year she and Owain happily posed for Hello! magazine and talked openly about their private life together.

Lucy gushed: "Don't let anyone tell you marriage is not more than a piece of paper. I feel really peaceful. I know it's the real deal."

But recently 30-year-old Welsh actor Owain has found work taking away from home for long periods.

Our source added: "This kills Lucy because she is thousands of miles from her family and feels so lonely in LA without her husband.

"Even when he is in LA, there are nights when Owain does not even come home and stays at his old place.

"They still live together most of the time and I'm sure they get through this is. Lucy is a fighter and a brave girl. She is determined to make it work-and she'll get her weight back under control as well."
