LeAnn Rimes has been trying to get pregnant for years now but unfortunately it doesn't look like her husband Eddie Cibrian is just as excited as her to have a baby. There's new speculation that the country singer is devastated that her husband doesn't share "the same baby fever" she has while he's looking for a way out of the marriage.

According to Star Magazine on Thursday, the site says that Rimes is "finally" pregnant (although unconfirmed) and that Cibrian isn't showing any excitement over the big news, either.

A source told the site, "Eddie never shared LeAnn's baby fever. He already has two sons and has never shown much interest in having any more children."

What's more, Cibrian is allegedly undermining Rimes whenever she talks about her baby plans and that he is completely fed up with all her nagging about wanting to start a family with him.

The insider added, "She would never admit it, but she has really strong worries about hanging on to Eddie," the source reveals. "After all, he cheated on Brandi multiple times, and he was married to her when they first got together! She is very afraid of what might happen if her influence on him lessens in any way."

What's more, it looks as though Rimes is fighting for what she wants - which includes a family of her own - as she and Cibrian try to work out their differences.

"LeAnn has waited too long and worked too hard to give up at this point," the source concludes. "She's not giving up on her marriage or her expanding family. One way or another, she will see to it that 2015 is the year she finally gets everything she ever wanted."
