Chris Jamison and Adam Levine sing 'Lost Without U' (VIDEO)

Chris Jamison and Adam Levine sang 'Lost Without U' by Robin Thicke on The Voice Season 7 Finals on Monday, December 15, 2014 for Team Adam Levine.

Adam has a video message for Chris, talking about how proud of him he is, and noting that he knew they'd be a perfect fit from the moment he first heard him sing. He wishes Chris all the best, and expresses his excitement at getting to sing "Lost Without U" by Robin Thicke with him. I'm stoked to hear it, honestly. Hell, I'm always stoked to hear Adam sing in acoustic settings. Granted, he's singing three times tonight, so this is aces for me (even though he might as well be a contestant himself at this point!).

You know, I never noticed how much Chris and Adam sound like each other. I mean, I know they both have killer falsettos, which is why Chris was able to tackle "Sugar" so effortlessly. But here, it was really pronounced. They could be brothers. If nothing else, they're dressed like twins. This is a really challenging song, and these two made it look like cake. Loved this performance. In fact, I forgot how much I liked this song. I'll probably end up downloading it.

But what do you think of Chris Jamison and Adam Levine?
