Gwen Stefani and Blake Shelton Are the Most Flirtatious Duo Ever: Watch Their Adorable Voice Chemistry

Chemistry, indeed! Gwen Stefani and Blake Shelton aren’t hiding their obvious crushes on one another. The Season 9 Voice mentors — both newly and conveniently single — couldn’t be cuter while filming the hit NBC competition show.

“Blake…is very handsome,” Stefani has gushed of Miranda Lambert’s ex-husband on air, adding that he’s very “sweet,” while the live studio audience cheers them on.

As exclusively revealed in the new issue of Us Weekly, the costars aren’t just doing it for the ratings. “They’re a real thing,” a source tells Us of the country crooner, 39, and “Rich Girl” songstress, 46.

So much so, the stylish L.A.M.B designer is even rubbing off on the down-home country star. “He’s dressing differently. Gwen says he can still wear plaid, but the right plaid!” another source says.
