Stefani released "Make Me Like You" Thursday, which is the second single off her forthcoming album, "This Is What the Truth Feels Like."
The upbeat tune tells the story of the No Doubt front-woman falling for someone after feeling "lost and uncertain," and Stefani's fans believe the lyrics are specifically about her relationship with Shelton.
"I was fine before I met you. I was broken but fine. I was lost and uncertain. But my heart was still mine," Stefani sings.
"I really like you, but I'm so scared. Why'd you have to go and make me like you? Yeah, this is a feeling I'm not used to. Why'd you have to go and make me like you? I'm so mad at you 'cause now you got me missing you."
Shelton seemed to confirm the rumors that "Make Me Like You" is about him, by revealing on Twitter that he bought the single on iTunes, and telling fans they probably know why he did.
"You can probably understand the multiple reasons why I just bought this... I hope you do to!!!" Shelton wrote.
Stefani, 46, and Shelton, 39, confirmed their relationship in November.
Stefani responded to her fans’ positive reactions after the single release on Twitter, thanking them for their words of support.
"U guys make me so happy," Stefani wrote. "THANKU for all your tweets."
"Reading all your tweets," she continued, adding the hashtags "surreal" and "thanku"
