The 'Used to Love You' hitmaker couldn't help but gush about her 39-year-old boyfriend, admitting she is their "biggest fan".

She said: "I'm our biggest fan. I actually feel like I'm not in my own life, because I'm not. I'm in a different life all of a sudden. I'm so blessed and I feel like I believe in my path. Now there's all these miracles around me!

"Trust me, I still can't believe that happened and is still happening. For whatever reason, I was chosen to be in this position, and I'm so honored and more confident. And I look at it, like, it always works out."

The 46-year-old singer also admitted she is unsure how she "survived" the "earthquake" that rocked her family last year when she divorced Gavin Rossdale.

She added to Us Weekly magazine: "There was so much of an earthquake in my life. How did I survive that? I don't know, but here we are and my life is full of so many blessings. I'm trying to really just be positive and grateful and look at it all, like this was all supposed to happen."

Meanwhile, the 'Came Here to Forget' singer previously revealed he and Gwen bonded over their failed marriages after he also split from Miranda Lambert last year.

He said: "We were starting The Voice last year, and I had to sit down and go, 'Look, by the time this thing airs, my life will have completely changed, and we need to talk about this now because it may affect what we talk about on the show.' I just felt like there doesn't need to be secrets. And then the same thing [happened] with Gwen. It was like, 'Here's what's going on, this show ain't gonna air until three months from now, so let's get this talked about right now.'

"That's how we even found out what was going on. And we just started to develop a friendship after that. And it took awhile, because it's chaos. But just over time, seeing each other a lot at work, it just kind of developed into that."
