During a two-hour broadcast on April 3, Gwen shared some intimate details about her and Blake’s lip-smacking rendezvous. The confession happened after “The Voice” hopeful Hunter Plake serenaded viewers and coaches with his captivating version of Foreigner’s ’80s hit, “I Want to Know What Love Is.”

Recalling moments from her own personal life, Gwen said, “You took a song that’s actually on my make out playlist.” Blake then turned toward his love and quipped, “I told you I knew that song.”

Of course, the two’s steamy admission made co-star Adam Levine groan. He even let out a grossed out, “Ew” – as if to tell his pals that they were sharing too much information. As for Alicia Keys, she thought the playlist was adorable, “That’s cute, Gwen. Share me that, ” she said.

Adam may have expressed his distaste for Blake and Gwen’s intimacy, but we’re pretty sure it won’t stop the lovebirds from telling the world that they “know what love is.” Hey, they couldn’t be happier! And, that makes us happy.
