Demi Moore and Ashton Kutcher's Pregnancy Struggle

Demi Moore and Ashton Kutcher's marriage is allegedly under pressure because of their failure to have a baby.

A source told America's Star magazine: "Demi seems very controlling. She likes to tell Ashton what to do, stand here, meet this person, do that. She wears the pants in that relationship.

"Ashton desperately wants a baby but is having to cope with the possibility that Demi may never bear his child."

Demi has been making a number of sacrifices and lifestyle changes to enhance her chances of conceiving - and is reportedly expecting Ashton to do the same.
