The Voice celebrity coaches have obviously spent a lot of time together. During their time on the singing competition, they've memorized each other's mannerisms and tendencies, which they hilariously displayed for us by impersonating each other in a new promo.

Be sure to tune in when The Voice returns to NBC on September 10 at 8 p.m. ET.
