LeAnn Rimes and Eddie Cibrian on the rocks

OHMYGOSSIP — LeAnn Rimes‘ romance with Eddie Cibrian is reportedly on the rocks. According to a new report from America’s Star magazine, the Playboy Club star is “sick and tired of the chaos” that comes with the How Do I Live singer.

“It never seems to end,” a source said. “He can’t take all of the drama anymore. He told her he needs some time alone to get his head together.”

LeAnn, 30, is trying to “save” her marriage by having a baby.

“She’s taking vitamins and charting her cycle, and she’s even putting on a few pounds, hoping it will help her conceive,” the source said.

“Her goal is to be pregnant in 2013, no matter what — even if she has to try IVF. She blames some of her emotional problems on not having a baby of her own.

“Eddie has to pay child support for [his sons with Brandi Glanville,] Mason and Jake. And let’s face it, his career is at a standstill. LeAnn is the breadwinner and he’s not about to destroy that gravy train. But he’s checked out emotionally.

“Being with LeAnn is a lot of work. Eddie’s staring to question whether it’s even worth it.”
