Oops! Blake Shelton might be in hot water with his girlfriend Gwen Stefani after he couldn't name her song during a recent appearance on the Tonight Show With Jimmy Fallon.<br /><br />The singer visited the show to promote his new album, Texoma Shore, but things got a little awkward when he and Jimmy started to play, "Name That Song."<br /><br />The house band, The Roots, played instrumental versions of popular songs as The Voice judge and late night host raced to guess the name of the tune.<br /><br />However, when the band started to play "Hollaback Girl," one of Gwen's biggest hits, the 41-year-old country star stood there cluelessly.<br /><br />"What's that?" he asked.<br /><br />"All I know is that Blake is in a lot of trouble right now," Jimmy laughed as he realized what song it was.<br /><br />Blake, embarrassed and defeated, then sat down on the stage. "I came to this show to promote my album and I am losing everything in my life!" he exclaimed.<br /><br />Watch the hilarious video above and share your thoughts in the comment section!
