Dua Lipa recently filled in for Jimmy Kimmel on Jimmy Kimmel Live, and chatted with Gwen Stefani. During the interview, the pair talked about topics like Gwen’s favorite music growing up, getting into country music, and her children. She also opens up about spending quarantine with her boyfriend, Blake Shelton.

While asking questions, Dua Lipa accidentally called Blake Gwen’s husband. She said, “So I heard that you’ve been spending quarantine with your husband, Blake Shelton, at the ranch in Oklahoma. Who else was with you? How was that?”

When Dua said, “husband,” Gwen smiled and let Dua finish talking. She then corrected the singer, saying, “Um … well, he’s not my husband.” She then added while laughing, “But that sounded cool when you said it!”

During the interview, she also opens up about what she thinks is her most annoying trait to Blake.

As we previously reported, Dua Lipa is releasing a Future Nostalgia remix album on August 21, and Gwen Stefani will be on the remix of “Physical.”
