This may be one of THE BEST mashups I've ever heard!! Blake Shelton and Kelly Clarkson joined their Voice co-stars on The Tonight Show, and created a masterpiece!! They performed an acapella mashup of all their hits and it's A-M-A-Z-I-N-G
It feels like a "Brady Bunch" set up but then you instantly get sucked in and blown away!! See for yourself! You won't be able to just watch it once!
