'The Voice' Season 11 Sneak Peek: Worlds Collide and Everything Changes!

Season 11 of "The Voice” is already fierce!

In a new teaser, bromance buddies Blake Shelton and Adam Levine don matching black suits and shades as they prepare for the arrival of new coaches Miley Cyrus and Alicia Keys — who have yet to make their official appearance with the veterans.

Keys previously mentored for Pharrell Williams' team during Season 7, while Miley joined forces with all four judges last season as a special advisor.

When the new coaches land, everything will change. Watch the “Men in Black”-themed teaser video to get you pumped up for the premiere of "The Voice" on Monday, September 19, at 8 p.m. on NBC!
