Country superstar Blake Shelton has been very impressed with the talent that has shown up for The Voice this new season.

"Been filming more of The Voice today... It's killing me. These people are TOO good!!!!! I'm not shi**ing you!!!!" Shelton said.

The four coaches of The Voice have reunited and have been taping for NBC's reality singing competition. The contestants are literally inspiring the coaches.

"The battle rounds have inspired me to improve my own craft. Had those guys on my mind at band practice," Adam Levine of Maroon 5 said.

New mentors for each team have added new flavors to the mix.

"So excited to have such a talented mentor on #TeamXtina. @BJAofficial has so much to offer team & has kept me laughing all day. #TheVoice" tweeted coach Christina Aguilera.
