Gwen Stefani is expecting a miracle baby to save her and Blake Shelton's increasingly problematic marriage, a new report claimed.

Sources quoted in the most recent issue of National Enquirer stated the new photographs of Gwen Stefani leave no question about what seems to be a developing baby belly. The supposed bundle of joy reportedly could not have arrived at a better moment for the troubled couple.

An unnamed insider told the entertainment news outlet, "They've been locked horns over everything from where they should live to how much time they spend together to Gwen wanting to cross over into Blake's territory and make a country music album. The ONLY thing they seem to agree on is that they want a baby together."

National Enquirer earlier stated that Gwen Stefani and Blake Shelton encountered obstacles during their childbearing efforts.

The unidentified tipster revealed, "These guys went through years of disappointment and IVF treatments that always seemed to go nowhere and were physically taxing on Gwen – but it appears this time it worked, and they couldn't be happier about it. It's a breath of fresh air for a couple that seems to have struggled to find happiness together!"

The report also stated that Blake Shelton revealed he was leaving his role as a coach on "The Voice" to focus on mending his deteriorating marriage. Another anonymous informant shared, "They decided they needed to step away from the show so they could focus on each other."

After Blake Shelton made this decision, according to sources, the Hollywood couple redoubled their efforts to expand their family. Gwen Stefani reportedly could not be happier with how Blake has stepped into the role of father figure to her three children with ex-husband Gavin Rossdale -- Kingston, Zuma, and Apollo.

A mole dished, "They both agreed that parenting is the thing that brings them closest together. So, they decided to give it another go – before it's too late for Gwen OR the marriage!"

Tattlers shared that although Gwen Stefani is a wonderful mother to her three sons, she remains a "girly girl," and she and Blake Shelton have frequently discussed how wonderful it would be to have a daughter.

One source said, "Blake loves roughhousing and hunting with Gwen's boys on his Oklahoma ranch, but he knows how much she would want to have a little girl around the house – and he's thrilled that they have a chance to make her dreams come true. They believe that Gwen getting pregnant could be the answer to all their prayers!"

Gwen Stefani has not yet commented on rumours that she has risked everything to save her purportedly rocky marriage with Blake Shelton. So, avid followers of the Hollywood couple should take these unconfirmed allegations with a pinch of salt until everything is confirmed to be accurate.
