Gwen Stefani turned down Blake Shelton’s surprise proposal, according to a new report. Is the honeymoon phase already over or does she have a valid reason behind her shocking decision?

Gwen Stefani and Gavin Rossdale’s split was finalised on April 20 and no one is more thrilled about the news than the No Doubt singer’s boyfriend, Blake Shelton.

According to Radar Online, the 39-year-old country crooner was prepared to pop the question with a whopping US$1.2 million (AU$1,675,440.00) Tiffany diamond ring. The site’s source revealed that Blake Shelton hid the massive rock at the bottom of a bucket of KFC fried chicken. But when Gwen Stefani found it, she reportedly didn’t give the reaction he was hoping for.

“Gwen was very touched, but [told Blake] she had to wait [for marriage] to make sure it was right for the kids,” the source told the site.

It’s no secret that Gwen Stefani adores her kids and she doesn’t want them to be in an awkward situation, considering the fact that her divorced from their father was just finalised. Gwen Stefani clearly wants to wait until her kids, 9-year-old Kingston, 7-year-old Zuma, and 2-year-old Apollo, are ready to accept Shelton as their father figure.

“[Gwen] definitely tells her kids what’s going on and runs things by them all the time,” the source told Hollywood Life. “She wants their [well-being] accounted for, and if and when she goes through another marriage, she wants the kids to be on board. They really like Blake, but she definitely wants to make sure they’re okay since the divorce is still very fresh for the kids.”

It turns out that it’s not just the kids that Gwen Stefani is worried about. The 46-year-old rockstar is also concerned about her age that she might not be able to conceive a baby anymore and taking away the chance of Shelton to become a dad.

“Gwen fears their age will get in the way of long-term happiness,” the source shared to Radar Online. “She’s 14 years older than Blake’s ex-wife, Miranda Lambert!” Gwen allegedly “believes the time may have passed for her to have another baby. She’s worried Blake won’t be happy in a marriage where he might never be a father.”
