Christina Aguilera appears on the cover of Rolling Stone's latest issue with fellow 'The Voice' coaches Cee Lo Green, Adam Levine and Blake Shelton. Christina tells the magazine she's isn't afraid to butt heads with the boys and is happy to be the only female coach: 'you have to be a pretty strong girl to stay up in the mix with the guys. It's a lot. It's a crazy locker-room kind of situation.'
