After three wins in four seasons of 'The Voice,' Blake Shelton seems to be invincible -- at least in the singing competition arena. However, his fellow coach Usher is ready to knock the 'Boys 'Round Here' singer off his winning streak. 

Usher insists it's high time for Shelton to know what it's like to lose, saying on the 'TODAY' show, "That lucky devil. He's kind of living on a high cloud right now. Somebody's got to tear him down. If not Adam, Shakira."

If Shelton is still unbeatable during the upcoming fifth season, which will begin airing on Monday, Sept. 23, then Usher, who is sitting out of the upcoming season, will have a chance to nab 'The Voice' throne in Season 6.

Despite Usher's desire to see Shelton beat, he has nothing but compliments for the country crooner. "He's a great coach, and he's really taught me a lot," he gushes of Shelton. "I knew nothing about the show in detail. Of course, I'd seen it as a viewer, but the time and investment in building these artists and helping them interpret themselves, and also kind of giving lessons to America about what it takes to be an artist is why I really wanted to do it."

Although Shelton has a breather from the show in between seasons, he's still working away, making sure his Team Blake contestants are taken care of in the huge music industry world. In fact, the Swon Brothers confirmed that the country star is still laser-focused in seeing them succeed.

Really, when it comes down to it, Shelton isn't as concerned about winning or losing, he just wants to help hopeful singers see success -- and he'll work incredibly hard to make that happen.
