Gwen Stefani and Blake Shelton remain strong as a couple amidst reports claiming that Miranda Lambert talked to Shelton behind Stefani's back.

It was reported earlier that Shelton secretly met his ex-wife for a clean slate. Stefani, on the other hand, reportedly went into panic upon hearing this and sent a text message to Lambert telling, "to stay away from her man."

"Blake thought [Stefani would] be happy they'd gotten the chance to call some things water under the bridge," an insider stated. "Instead, though, it sent her into a panic."

"Gwen went on a rampage, and Miranda didn't hold back either," the insider stated. "God help them all if they come face-to-face anytime soon."

It has been over a year since Shelton and Lambert parted ways, and Stefani has yet to hint of any bad blood between them.

Instead, Lambert is reported to be more than happy in her relationship with Anderson East, while Stefani's romance with Shelton is going stronger that may possibly end up to wedding.

Gwen Stefani and Blake Shelton will reportedly tie the knot just before their anniversary as a couple.

"They want to get married before the end of the year," a source told Us Weekly.

"They are both very, very happy. Blake is having the time of his life with Gwen and feels so comfortable around her," the insider added.

The pop diva has reportedly hired wedding planner Jerri Woolworth for their nuptials.

"Gwen has said they both want something more low-key than their first weddings," an insider added. "It would likely be at Blake's ranch [in Oklahoma] or in the backyard. Gwen doesn't really care, she is just in love with Blake and their life together."

Moreover, Mark Burnett, the producer of NBC's "The Voice," seemed to drop hints about the couple's plan for marriage.

The TV producer went on telling US Weekly that he is "really really hoping" Stefani and Shelton invited him to their wedding.

Moreover, both the couple's friends are sure an engagement is going to happen soon.

"Naturally, she'll say yes," the source said. "They've been talking about getting married for months."

Though Blake Shelton and Gwen Stefani remain mum about the wedding rumors, it has been noted that it would be Shelton's third time down the aisle after not having children with ex-wife Kaynette Gern and Miranda Lambert.
