Music power couple Gwen Stefani and Blake Shelton has been making news almost every day as they flaunt PDA in every corner of the world. With the affectionate display of their love, speculations are rife about an upcoming nuptial for the duo. If rumours are to be believed, the celebrity couple will soon tie the knot in a country-style ceremony during the holidays.

Stefani and Shelton "plan to wed at his Oklahoma ranch around Christmas", says a gossip report(via Hollywood Life). While neither of them has officially confirmed the news, the article claims that a wedding announcement is on the cards and it is apparently "Gwen's suggestion".

The tabloid went on to claim that the Hollaback Girl hitmaker's three sons - Kingston, 10, Zuma, 8, and Apollo, 2 – are also onboard with the idea of Shelton becoming their stepfather.

"Apollo wants to be the ring bearer, and the two older boys will be junior groomsmen with Blake," a source told the magazine adding, "Blake wants it to be really special, to show them coming together as a family."

If and when the A-lister couple's country wedding takes place, their guest list will surely be one star-studded affair. Hollywood Life quoted the report saying that the two "are finalizing the guest list, which includes the Voice judges."

This should come as no surprise to the fans as Stefani and Shelton's romance bloomed on the sets of the NBC reality show. At that time, Shelton had just called it quits on his relationship with former wife Miranda Lambert, while Stefani too had announced her split from Gavin Rossdale.

The duo even appeared together for a short duration on The Voice in season 10 and crooned to the audience her duet with Go Ahead And Break My Heart.
