It's hard not to tease Blake Shelton about his relationship with Gwen Stefani.
When the Voice mentor appeared on The Tonight Show in Orlando Tuesday, Jimmy Fallon found a clever way to work Stefani into the conversation. It began when he asked Shelton about his album, If I'm Honest, and the track he was set to sing, "Every Time I Hear That Song."
"What's the name of that song again? I love it," Fallon lied. "I was singing it today."
"Oh, really?" Shelton asked. "Let's hear a little bit of it."
Fallon improvised his own lyrics, using Paul Young's 1985 cover of Hall & Oates' "Everytime You Go Away" as his melody: "Every time I hear that song / You take a piece of me with you / Ooh, ooh / Every time I hear that song / Whoa-oh / You take a piece of me with you/ Ooh, ooh, ooh."
