Gwen Stefani and Blake Shelton
Blake and Gwen officially met whilst coaching on 'The Voice' in 2014 whilst married to other people.
The No Doubt singer was wed to Bush frontman Gavin Rossdale, while Blake was together with country star Miranda Shelton.
Gwen, who split from Gavin in 2015, bonded over her recent divorce with Blake, who split from Miranda that same year. The couple quickly began dating that same year before tying the knot in July 2022.
He said: "That's kind of how our friendship and bond started, that day.
"It went from that, to checking in on each other once a week through email - 'This s*** happened to me, what happened to you?' — to maybe three times a week, then every day, to 'Hey, here's my phone number if you ever want to text.' Next thing I know, I wake up and she's all I care about, and I'm wondering if she feels the same about me."
