They’re dating! Blake Shelton and Gwen Stefani, that is ...

Rumor no more: Blake Shelton and Gwen Stefani are officially a thing.

Like, officially officially: Stefani’s rep confirmed “The Voice� costars’ brand-new couplehood to a number of outlets Wednesday, a day after the No Doubt singer flew to Nashville to join Shelton for some CMA Awards festivities.

Seriously, even the by-the-books Associated Press is reporting that they’re dating.

Shelton and Stefani were, of course, photographed all over the place last weekend as they both hit three separate Halloween parties over two nights and were spotted holding hands as she led him out of the one thrown by actor Jared Leto.

The 46-year-old mother of three was, however, still playing it close to the vest on Tuesday when she talked with Ryan Seacrest on his radio show.

“I think that NBC did that,� she said of the weekend’s rumors, referencing the network that airs “The Voice.�

“Two divorced people at the same time. But to be super honest, it is kind of crazy we both went through the same thing at the same time. There’s been so many people that I’ve gotten comfort from.�

A People source echoed that notion later on in confirming that the two had “begun� dating. “They’ve been supporting each other through a difficult time and they’re really happy together.�

Both performers went back on the romance market this year, with Shelton and Miranda Lambert announcing their finalized divorce in July after four years as man and wife, and Stefani and Gavin Rossdale revealing in August that they were ending their nearly 13-year marriage.

A source said to be close to Lambert told E! News early Wednesday that the country gal “was not surprised to hear of the romance� between her ex and his coworker. “They were always pretty flirty,� the source said. “Miranda and Blake were on the rocks on and off and knew that this could always be a possibility.�

The dating news doesn’t mean the 39-year-old “Doin’ What She Likes� singer will have a new lady on his arm at the CMA Awards on Wednesday for the first time since 2007, when he started attending with Lambert. TMZ says Stefani will accompany him only to the after-parties, but not because she’s concerned about running into that other blond on the red carpet.

“She just didn’t have the right clothes for the award ceremony because it was so last minute,� a source told the website. So, it ain’t about Miranda -- it’s all about the outfit.

Wonder if this will affect Blake’s office bromance with Adam Levine...
