Gwen Stefani and Blake Shelton just got engaged last month, but the tabloids are already claiming that their wedding may not push through.

According to Globe, since their engagement, Stefani and Shelton have been bickering nonstop. And some of their arguments revolve around money, property, and their prenuptial agreement.

A source claimed that Stefani wants Shelton to sign a prenup so she could protect her assets. However, the country musician doesn’t think that this is the right thing to do.

 As such, the No Doubt singer, allegedly, gave Shelton an ultimatum that she won’t push through with their wedding unless he signs the document.

A prenup is, allegedly, very important for Stefani, especially since she’s been divorced before. But what makes things worse is the fact that the singer, allegedly, has more outrageous demands for Shelton.

Stefani, allegedly, wants to keep the house that she and Shelton purchased in the event of a divorce. She also wants all the furniture and appliances in their home, including an espresso machine.

As for Shelton, the singer is thinking about agreeing to Stefani’s claims because this is the only way for their wedding to push through.

And the “God’s Country” singer can already, allegedly, see what will happen if his fiancée doesn’t get her way, so he’s also, allegedly, having second thoughts about their relationship.

Meanwhile, Star also published a similar story this week. The tabloid claimed that Stefani and Shelton’s combined assets are estimated at $400. And even though they’re already secured until the end of their days, Stefani still wants a prenup in place.

However, the source insisted that Shelton doesn’t agree because he doesn’t think that there’s a need for Plan B. After all, he’s so sure about Stefani and he believes that their marriage will last forever.

The insider also said that despite his reservations, Shelton is willing to sign the prenup in order for Stefani to walk down the aisle with him.

All of these issues are, allegedly, causing tension in the couple's relationship when they should be in bliss after their engagement. 

In related news, National Enquirer claimed that Shelton’s ex-wife, Miranda Lambert, doesn’t think his and Stefani’s marriage would last. After all, Lambert is convinced that it won’t take very long before Shelton misses his old life.

Lambert also believes that Shelton will eventually get tired of Stefani’s face because it’s, allegedly, unnatural.
