I was kind of surprised she didn't pick Adam (well in my mind if he was an option I don't know why anyone wouldn't pick Adam, but that's just me). I'm not really a Blake Shelton fan, but he's lucky to have Cassadee on his team.
I don't really know how the show works but hopefully she stays on and we can see lots more from this talented girl in the future.
Also side note, her boyfriend, Rian Dawson (the one in the beanie), was super adorable when they showed him backstage. They make for a super cute couple. Plus I love All Time Low.
