The lines of music genres are blurring, as artists from different worlds are starting to team up more and more frequently. Colombian beauty Shakira recently let her Twitter followers know she was busy in the studio -- with Blake Shelton!
Blake Shelton called it: Adam Levine is sexy -- and now, People Magazine is jumping aboard, naming the pop singer the Sexiest Man Alive. But that doesn't mean that Levine agrees that he's the most sizzling star.
Blake Shelton and Adam Levine are back on the boob tube every Monday and Tuesday, competing on the fifth season of 'The Voice' ... and bickering left and right. But it's all in love (we think, anyway, since you never can tell with self-deprecating Shelton)!
