Blake Shelton & Gwen Stefani Plan Vegas Wedding

Singing sweethearts Blake Shelton and Gwen Stefani are planning to elope on her 47th birthday in October. Now The National ENQUIRER has the scoop on the the hush-hush Las Vegas event — including who’s off the guest list! That includes their ex-spouses Miranda Lambert and Gavin Rossdale!

“Blake and Gwen have told their families straight out that Gavin and Miranda are banned,” a source dished to The ENQUIRER. “For a while after their marriages broke down, they felt ‘hopeless,’ so they want nothing to spoil the fact they are moving on,” said the spy.

Gwen, a devout Catholic, already has her eye on one of the most iconic chapels in Las Vegas, according to insiders — The Little Church of the West. The chapel is on the south end of the Las Vegas Strip, and perfect for couples that want a “small wedding” with a “few guests.”

Sources said that Gwen is determined to find a place where her parents and her kids will be front and center when she declares, “I do!”

The wedding’s going to be a family affair, too! Gwen’s thrilled that Blake, 39, has grown so close to her mom, Patti, and dad, Dennis, over the past few months, noted the insider. She's also relieved that Blake's relationship with her sons — 9-year-old Kingston, 7-year-old Zuma and 2-year-old Apollo (pictured) — is solid.

Blake is keen to have his mother,  Dorothy Shackleford (pictured), watch them wed — and sources said that Mom has even given the showbiz couple her blessing!

But even though Vegas weddings are considered to be cheap, insiders say that Gwen has promised pals that her nuptials will have a feminine touch. She's told pals there’s no way she’ll have a tacky Sin City wedding!

Sources told The ENQUIRER that Blake (seen here with Gwen in Las Vegas this past May) is staying out of the planning. He’s a no-frills guy who wore Wrangler jeans and cowboy boots when he married his first wife, Kaynette Gern, in 2003.

Blake's second wedding to Miranda was a more lavish affair, but he wants his third — and hopefully last — wedding to be “memorable.” An insider said that Blake and Gwen agree that there’s “nowhere quite like Vegas!”
