When it comes to TMI, sometimes it's best you simply "Don't Speak!"

Blake Shelton and Gwen Stefani accidentally overshared on The Voice Monday night when the couple pointed out that one of the contestants sang a song straight off the No Doubt frontwoman's "makeout playlist."

"You took a song that’s actually on my makeout playlist," Stefani revealed after Hunter Plake belted out Foreigner's "I Want to Know What Love Is," prompting Shelton to add, "I told you I knew that song!"

While fellow coach Adam Levine was not amused, making a face and complaining "Ew!", at least Alicia Keys thought it was "cute."

Then again, we shouldn't be surprised: Stefani does have a song called "Making Out," after all.
