Office star Lucy Davis piles on the pounds as she 'battles to save marriage'

Actress Lucy Davis appears to be losing her battle with weight following reports she is fighting to save her marriage.

The 35-year-old star of television show The Office lost three stone in the run-up to her 2006 wedding to Welsh actor Owain Yeoman.

But the pretty blonde - who is the daughter of comic Jasper Carrott - looked to have piled on the pounds as she was pictured in Los Angeles recently.

Sources said to be close to the star and her husband say they have been constantly arguing in recent months and Owain has been spending nights at his old flat.

‘Lucy and Owain have been rowing 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,' a friend is quoted as telling the News of the World.

‘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.’

'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.'
