Amid growing rumors that Gwen Stefani and Blake Shelton are planning to get married this Christmas, a report by Life & Style magazine said that the couple is currently working toward their prenuptial agreement. The two confirmed last November that they were dating.

“The prenup will dictate that their earnings remain separate,” a source told Life & Style, adding that their total fortune is $225 million.

Neither of the two will ask for spousal support should they divorce, plus Stefani’s Beverly Hills mansion will remain under her name and Shelton will keep his Oklahoma ranch under his name, the report added.

“Blake said he didn’t want [a prenup], but Gwen wants to make sure they are both protected,” the source said, adding that the 46-year-old singer did not have the agreement with her ex-husband Gavin Rossdale.

Previously, the magazine reported that Stefani and Shelton will announce their engagement in September and marry sometime around Christmas.

“They’re planning a December wedding at Blake’s ranch in Oklahoma because Gwen and the boys love it there and it will give them a lot of privacy,” a source told the magazine at the time.

Last month, Stefani talked candidly about her personal life and career in an interview to a newspaper.

“It’s incredible to be in the position to be able to be a songwriter and share your story with people and then have people relate to it,” Stefani told Tampa Bay Times. “It makes you feel better about yourself in your own life, and you feel comforted. I just am really in the moment right now. I’m kind of in disbelief that this is all happening. I’m super, super grateful.”
