Gwen Stefani-Blake Shelton Update: ‘The Voice’ Judges Reportedly Writing Song About Relationships

Blake Shelton and Gwen Stefani are taking their romance to the country charts. "The Voice" co-stars, who confirmed they're dating ahead of the CMAs, supposedly spent some time in the recording studio writing a country ballad together.

According to People, the new couple wrote the song shortly after the current season of "The Voice" kicked off in September. A source told the outlet that the "mid-tempo ballad" is about telling a lover to get out of relationship if that's what they want.

"It's amazing how good she sounds on a pretty country song," the source told People. "And it sure is good to hear Blake singing real country again.”

So far, there's no word on when Shelton and Stefani plan to release their duet.

As previously reported, Shelton and the No Doubt singer finally admitted to the dating rumors Wednesday. There were also reports the "Hollaback Girl" singer was in Nashville with Shelton, who was in town to perform at the Country Music Association Awards.

It seems Shelton and Stefani's romance started after they bonded over their respective divorces. Shelton and Miranda Lambert ended their four-year marriage in July, and Stefani announced in August she was divorcing Gavin Rossdale after 13 years of marriage.

“Blake and Gwen have begun dating. They’ve been supporting each other through a difficult time, and they’re really happy together," a rep for Stefani told Perez Hilton.

Earlier this week, Stefani opened up about her bond with Shelton, telling Ryan Seacrest’s radio show that it was “crazy” they both went through difficult things at the same time.

"There’s been so many people that I’ve gotten so much comfort from. Just people coming to me and telling me their story,” she said. “Not confiding, but sharing, which has just helped me see things from a different perspective and move forward.”
