Leann Rimes's marriage is reportedly on the rocks.

The 30-year-old 'How Do I Live' singer's relationship with 'Playboy Club' star Eddie Cibrian is said to have hit a rough patch just months she completed a 30-day stint in an in-patient facility for stress and anxiety.

A source close to the couple, who have been married since April 2011, told gossip website RadarOnline.com that the actor is ''sick and tired of the chaos'' that surrounds his wife, who is currently suing a twitter user for bullying her online.

The insider said: ''It never seems to end. He can't take all of the drama anymore. He told her he needs some time alone to get his head together.''

The singer is reportedly hoping to have a baby with her 39-year-old husband, who already has two sons Jake and Mason with his ex-wife Brandi Glanville, in a bid to repair their relationship.

The source said: ''She's taking vitamins and charting her cycle, and she's even putting on a few pounds, hoping it will help her conceive. 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 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 starting to question whether it's even worth it.''
