But the singer shoots down reports that they've collaborated on a new song in a new interview with Dallas radio station 103.7 KVIL.
Gwen Stefani is clearing the air about her relationship with Blake Shelton.
Two days after reps for the pair confirmed their relationship, Stefani opens up in a new interview with Dallas/Fort Worth radio station 103.7 KVIL that was shared exclusively with ET.
"He's a pretty rad guy, I have to say that," Stefani tells #Uncorked hosts Leigh Ann and Courtney in an interview airing on Monday at 4 p.m. CT.

"There's been loads of people that have helped me with this tragedy," Stefani says of her divorce from Gavin Rossdale, which was recently finalized. "There's definitely key people that have pointed me into the right direction. Blake really helped me. Not to change the subject, but it's kinda on the same subject, Pharrell was literally like a guardian angel."
When asked about going public with Shelton, Stefani claimed, "We didn't! Like, somebody did. That's what's so crazy like, who announces that? Why would I do that?"
As ETonline previously reported, it was Stefani's rep who confirmed the relationship with a brief statement to Us Weekly: "Gwen and Blake are longtime friends who have very recently started dating." A rep for Shelton also confirmed the news to ET.

Stefani also attempted to shut down recent reports that she and Shelton have written a new country song together, with a flat-out "No!" (A source confirmed to ET earlier in the day that the pair had penned a song together, but it has not yet been confirmed whether they've recorded it.)
"He's not writing on my record," she said.
The radio hosts later hit Stefani with a quick-fire round of questioning, including the kicker: Southern men or British men?
"Oh, that's such a funny question!" Stefani teased, clearly picking up on the reference to her ex. "Let's see, I would say if I had to choose, Southern."
Stefani and Shelton stepped out for the first time as a couple at a CMA after party in Nashville, Tennessee, on Wednesday. ET exclusively revealed the photos of the couple walking hand-in-hand outside the party for Warner Music Nashville, Shelton's label. See for yourself in the video below.
