Nothing like a bit of Foreigner to get Gwen Stefani in the mood!

The 47-year-old singer confessed she has a “makeout playlist” during Monday night’s episode of The Voice.

The revelation came after Hunter Plake, a contestant on Stefani’s team, belted out Foreigner’s “I Want to Know What Love Is” for his Knockout Round performance.

“You took a song that’s actually on my makeout playlist,” Stefani divulged afterwards, before choosing Plake to stay on Team Gwen.

“I told you I knew that song,” piped in her boyfriend and fellow coach Blake Shelton.

The news was TMI for Adam Levine, who immediately declared, “Ew!” and pulled faces like he might barf.

Luckily, Alicia Keys was more positive. “That’s cute Gwen!” laughed the singer.

The giggles kept on coming when Keys’ huge ponytail began to give Shelton grief, as it blocked his eye line to Stefani.

“It’s all up in our business,” the 40-year-old country crooner complained.
