Gwen Stefani Opens Up About Her "Unexpected" Split from Gavin Rossdale, Grilled on Blake Shelton

The singer has been making headlines lately not only for her split from husband Gavin Rossdale, but also for her new relationship with fellow "Voice" coach Blake Shleton. Just last week, the former No Doubt front woman's rep confirmed the two were an item ahead of the country crooner's appearance at the CMA Awards.

"There's a lot going on with you," KIIS-FM's JoJo Wright noted of the 46-year-old's personal life when she stopped by the show Monday night.

"This is one of those weird moments where do you talk about who you're dating now? Do you talk about the breakup?" he asked the singer. "I'm not going to go with the Blake thing, because I get it. [KIIS-FM's Ryan Seacrest] and everybody's already covered it. Hey, let the girl live! Let the girl date. He seems like a nice guy. Congratulations. Let's go have a drink. But I do want to ask about the previous relationship with Gavin, because that's what the song's about."

But Gwen seemed like she was open to talking about her new relationship although she didn't say much about the 39-year-old. "Ask me whatever you want and I'll decide if I want to answer it. How about that?" she said.

"I am curious about Blake. One thing: What does he drink? He always has something in his cup. Probably ain't coffee. Do you even know what's in there?" Wright asked -- but Stefani never answered the question as the show cut to a commercial. When they returned, the mom-of-three did open up about her latest single, "Used To Love You", which many think is about the end of her 13 year marriage to Rossdale.

"The song was not written that long ago. Like, I want to say maybe a month and half ago, which is crazy," she admitted. "I had been writing, writing because my life blew up," she said. "Everybody knows that my life blew up last February. I'd just been dealing with that. Unexpected. I was going along thinking that was going to be the rest of my life and it's not. I don't know what happened. I've always wanted to write music so desperately because doing it is one thing that really validates me for myself."

The blonde beauty didn't go too into specifics about her writing process, but did elaborate on what triggered her to write the powerful song.

"There was one night, the epicenter of the whole thing—that's the most I can say about that—and the next day I wrote the chorus to 'Used to Love You,' but I didn't know it was 'Used to Love You.' I just had written all this stuff and it had happened to be in there buried in a bunch of lyrics that I had written."

In a new radio tour today, Gwen continued to be asked about her new relationship with Blake -- where she once again said she never confirmed they were an item.

"I never said nothing about being in a new relationship. I don't know who said that, somebody did," she told Channel 933 in San Diego. "Then my kid came in last night to tell me about it. That's how crazy my life is, people can just say whatever they want. My truth is, 'Used to Love You,' that's the song, that's what I said."

"Who confirms that? Whatever. It's so embarrassing, the whole thing," she added to 97.9. "Let's talk about something else."

When asked flat out whether they're dating or not, she replied, "Oh my God, how rude! I'm not even gonna talk about it" ... before hanging up.
