(Cover) - EN Showbiz - Gwen Stefani and Gavin Rossdale are reportedly seeking help for their troubled marriage.

The 43-year-old No Doubt songstress and the 46-year-old Bush frontman wed in 2002. Gwen and Gavin share young sons Kingston and Zuma together.

Apparently the pair are experiencing a rough patch in their relationship.

They were spotted leaving a couple's therapy session looking visibly upset earlier this month.

"Over the past two years they've spent less and less time together," a source told In Touch magazine.

The discord is attributed to Gavin's unrelenting tour schedule.

The time he spends away from home performing with Bush is said to be having a massive impact on his and Gwen's relationship.

"They used to be affectionate with each other and laugh a lot," an insider explained. "That never happens anymore."

Gwen has spoken before about the undying effort she puts into her family.

She revealed that at times she considers herself alone in her endeavours.

"Sometimes, I feel like a single mother who tries to succeed in all fronts," she confessed to French magazine Be recently.

"I have the feeling that I will never succeed, that something is going to break at one point, but for now, it works..." (C) Cover Media
