The Voice coaches are supporting each other as some are dealing with high-profile breakups.

Blake Shelton and Gwen Stefani have gone through splits (Blake from Miranda Lambert and Gwen from Gavin Rossdale), but they told ET that heading back to work has helped them with their healing processes.

"I haven't met one coach that's been on this show that I wouldn't consider at this point a really good friend," Blake told ET, explaining how they support each other on the show. "Any of the coaches that I've worked with on this show I can call at any moment and talk to."

In July, Blake and Miranda announced they were divorcing after four years of marriage, and just weeks later, Gwen filed for divorce from her husband of 13 years. While Blake and Miranda have no children together, Gwen and Gavin share three sons, Kingston, 9, Zuma, 7, and Apollo, 1, who they will continue to raise jointly.

Gwen described The Voice as a silver lining to an otherwise disappointing summer.

"It's so amazing!" she said. "Honestly, I've had so much fun so far, and it's so motivating. I think this is the funnest thing I've ever done in my whole life work-wise."
