Uh-oh! Did this game cost Blake Shelton his girlfriend?

One would think Blake Shelton knows music pretty well with his impressive resume of 10 million records sold and over 1.7 billion streams worldwide. Blake is even dating longtime girlfriend, Gwen Stefani who’s had her own success with over 30 million albums sold between her solo work and time with rock group, No Doubt.

So when Blake stopped by the Tonight Show with Jimmy Fallon, he didn’t realize he would get himself into trouble in a game of “Name That Song”. Jimmy Fallon’s house band, The Roots, began playing Stefani’s 2005 hit, “Hollaback Girl” as Blake blankly stares at the band before asking, “what’s that?”

Should Blake have known one of his longtime girlfriend’s biggest songs? The hilarious moment begins at around 5:15 in the video.

Uh-oh… did Blake did just put himself in the dog house? Sound off below!
