Pharrell Williams says Blake Shelton and Gwen Stefani's romance is "a miracle".
Gwen Stefani
The 'Happy' hitmaker is thrilled that his fellow 'Voice' mentors have found love with each other after both getting divorced last year.
Speaking on the 'Today' show, he said: "It's poppin' off! It's so beautiful, because being there, I watched both of them go through a lot, you know. You hate to see your friends go through something so heavy, and it's kind of like a miracle, man - just watching that."
However, Pharrell was initially unaware that the duo had started a relationship.
He said: "I had no idea. And then Blake sends me a text message, and I'm like, 'Whoa!'"
Meanwhile, is was previously claimed that Gwen and Blake found comfort in each other following the end of their marriages to Gavin Rossdale and Miranda Lambert respectively.
A source said: "She was heartbroken for her children that the marriage wasn't going to work. She tried so hard for the kids to keep the marriage together. Then here came this ray of sunshine who did make her smile, and now he's one of the most positive people in her life.
"They have turned lemons into lemonade and have turned a bad situation for both of them into something great. They're both much happier."
