According to US Weekly, the new "The Voice" season 7 judge Gwen Stefani admitted to them that she and her husband Gavin Rossdale fought while she works on the "The Voice" set.

"The whole thing was a surprise."

"I just had my baby [Apollo], and I got the call. I had no idea sitting here would be so fun. I was really a bit anxious after I signed it and was like, 'Oh my god, what have I gotten myself into?'"

Source also added "Hollaback Girl" singer was given an advice from veteran judge Adam Levine. Adam told the story after the argument between the couple:

"The night before, 'Um...what is the deal here? This is crazy. What do I do?'" Levine chimed in. "And I was like, 'You'll be fine, don't worry.'"

He also added what Stefani had told him: "It's been seamless. I feel like I have nothing to stress over. I think the biggest surprise is how inspired I am about just being around the show, being around all the music, wearing this hat for the first time and looking back on everything I've done."

Another statement of "Hollaback Girl" singer shared by USMagazine:

"It was just awkward, because we had never done anything [together]," Stefani continued of her husband, with whom she shares three boys: Kingston, 8, Zuma 6, and Apollo, 7 months. "We had only collaborated on making babies together, we had never done anything outside [of that]. I was really nervous about having him there, we have different opinions about music. We like different music, and I was like, 'You know what? Let's embrace it. Let's just do it.'"
