Gwen Stefani has been spilling the beans on co-writing with her boyfriend, Blake Shelton.
She sat down for a chat with Seth Meyers.
"I love Blake", she said. "He is the most incredible guy. Everybody loves Blake, and that's the thing. There's no way around it. He's just a sparkly like happy, amazing person."
Before they started working together though, Gwen admitted that Blake wasn't on her radar at all.
"I didn't even know Blake Shelton existed in the world," she said.
But Gwen added that has since changed.
"Trust me I'm like the biggest Blake Shelton fan now, I know all of his music."
