Gwen Stefani & Blake Shelton Split? Miranda Lambert Ends Wedding Bliss, 'Threatening' Texts

Rumors now suggest that Gwen Stefani's relationship with Blake Shelton is crumbling - and all because of ex-wife, Miranda Lambert!

Apparently, the No Doubt rocker continues fighting with her "Sangria" lover after Lambert recently sent a series of very mean text messages. The alleged "harassment" initially started after Stefani kept referring to the "Automatic" songstress as a "redneck harlot." A supposed source for the seedy gossip tabloid Ok! magazine explains:

"Miranda got ahold of Gwen's cellphone number and started calling, sometimes as many as four times in one day."

Stefani got so annoyed with these strange calls, she eventually messaged back, "Who is this, and how did you get my number?'" The snitch reveals that Lambert quickly identified herself and began vehemently insulting the "Used to Love You" crooner. She deemed the 46-year-old "The Voice" beauty a "home-wrecker" who's career is officially "over" since her music hasn't been "relevant since the '90s," and even threatened, "[you're] lucky I don't find you and kick your ass."

Really!? But the (phony) insider doesn't stop there...

"Gwen accused [Shelton] of somehow letting her phone number slip to his ex, [and of even] defending Miranda." He ultimately told her to "calm down and tried to brush off the situation, explaining that it was just Miranda's tough 'country gal' personality coming through, and that Gwen shouldn't get too worked up about it."

And that's when Stefani really felt betrayed, insisting that Shelton was clearly "taking his ex-wife's side." So, she ended things on the spot:

"Gwen decided that if Blake wouldn't stand up for her and tell Miranda off, she didn't want to be with him."

But just earlier this month, reports insinuated that Stefani was actually getting ready to tie the knot with the 39-year-old country music superstar...

So, what's really up?

Well, GossipCop confirms that such "breakup" drama is complete "garbage," with a rep for Stefani claiming that the entire story is "false." The couple's happy with their blossoming romance, and Lambert's ready to move on, too!
