Gwen Stefani was feeling a lot of pressure after agreeing to record her duet with boyfriend Blake Shelton.
While the country crooner also recently admitted to feeling "insecure" about their song, "Go Ahead and Break My Heart," the No Doubt frontwoman said she couldn't pass up the opportunity to collaborate.
"The story is that he had written this song and sent it to me on my phone," Stefani told Chelsea Handler on her Netflix talk show, "Chelsea."
"He's like, 'I wrote this song' and I was like 'Whoa what if I don't like it, huge turn off!' I listened to it and thought 'Oh my God, I love this,'" she recalled. "He said, 'Write the rest of it.'"
Despite having reservations about writing, Gwen decided to dive in.
"I think when you have a really long year you start to compete with your own self and get insecure about 'I did that but how did I do that?'" she explained, brushing over her public split from husband Gavin Rossdale.
While she had a tough year, the mother-of-three is proud of the music she created during that time.
"When you have new music it's such a miracle and to be able to go live with it… the songs become a whole other version of themselves," she said of her new album, "This Is What the Truth Feels Like."
"I never thought I would have new music. I never thought any of this stuff would happen," she added. "It's the craziest year of my life."
