TMI? Not when it comes to Gwen Stefani. During Monday night's episode of The Voice, the pop star had no problem letting fans in on one of the songs the helps her get in the mood.

After Hunter Plake performed '80s rock song "I Want to Know What Love Is"—a song Stefani chose for him to sing—she made a confession that caused fellow judge Alicia Keys to swoon and judge Adam Levine to jokingly shrink back in his seat with disgust.

"You took a song that's actually on my make out playlist," revealed Gwen. "Ewwww!," the Maroon 5 frontman said, sticking out his tongue. "That's cute Gwen," Keys said, flashing a big smile.

But, it was Stefani's boyfriend Blake Shelton's response that took things over the top. "I told you I knew that song!" he shouted, as the audience giggled. The duo has been more open than ever about their romance after keeping things under wraps when they first started dating in late 2015.
