Gwen Stefani Pregnant HOAX! No Blake Shelton Engagement, Miranda Lambert Christmas Heartbreak

Perhaps Gwen Stefani's ready to have another kid with new boyfriend Blake Shelton, but the No Doubt rocker is NOT already pregnant with that "surprise" baby!

Stefani hopes to take things slow, but that doesn't mean that she's not already planning a future with the beloved "The Voice" coach. Especially now that she's 46-years-old!

"Gwen has told friends that Blake is the one and wants to make it official with having a baby," an alleged insider reveals to HollywoodLife.com. "She doesn't want to rush but later next year she would be happy to get pregnant if it is safe... She wants to make that commitment to Blake, she is ready to take that step."

And just a few days after this report went viral online, the seedy gossip tabloid Star revealed this explosive cover issue:

Gwen & Blake pregnant, but he'll never marry her! Blake's shocking reason why. Gloating Gwen tells Miranda [Lambert] on Christmas Day!

What!? The entire headline's rather harsh - and completely fabricated, according to GossipCop.

In fact, such unconfirmed insinuations prove just how false this latest "pregnancy bombshell" really is:

"Sources close to the singers believe they're expecting."

"Hearing that Stefani is pregnant would be Lambert's worst nightmare."

"Stefani wasn’t drinking over the holidays, and she relaxed her workout regimen too, so no one would be surprised if she turned out to be pregnant."

Funny enough, Shelton and his "Used To Love You" muse were just spotted together at a winery on Monday (December 28). And apparently, Stefani was definitely enjoying some "adult friendly" tastings during the tour.

Still, alleged insiders suggest that "seeing the lovebirds over the holidays seemed to convince some friends and family members that the rumors could be true.”

Yeah, right.

The "Sangria" crooner's relationship with the Hollywood mommy-of-three continues growing strong, but they're not adding another little bundle of joy to the mix anytime soon! But will he propose of New Year's?
